While trying to troubleshoot and build other workflows, I found that I was unable to activate any workflow, even a completely new and very simple one.
I created a new workflow specifically to test this issue, named “Test Gmail Activation V2” (ID: 7kLrR7PANW05AQaa). This workflow contains only:
A Manual Trigger
A Gmail node (Get Many operation, is:unread filter)
A Code node (simple email/subject extraction)
An IF node (checking a basic variable)
Here is the exact behavior I observe in this new workflow:
The workflow runs correctly when I click “Test Workflow”.
The tooltip that appears when hovering over the activation switch displays the correct message: “This workflow has no trigger nodes that require activation”. BUT:
The switch remains visually stuck on “Inactive”.
An error icon (red lightning bolt ) persists on the Manual Trigger node (clicking it displays the “Test workflow” button, which seems abnormal).
When I try to click the switch to “Active”, a “No Entry” symbol () appears, indicating that the action is blocked.
Given that the tooltip message is correct (it acknowledges the absence of a trigger requiring activation), but activation is actively blocked () and the visual state doesn’t update, I strongly suspect a deeper issue.
If I understood correctly, out of all possible triggers the workflow has only manual execution trigger. What would you expect to happen upon activation of such a workflow?
Thanks for the question. You’re right, a workflow with only a manual trigger doesn’t run automatically when activated, unlike a Cron or Webhook trigger.
My expectation upon activating such a workflow is simply that:
The UI toggle switch should change state from “Inactive” (grey) to “Active” (green).
The workflow should be marked as “ready” in the system, available for manual execution via the “Test workflow” button or potentially via API calls if needed later.
Most importantly, the persistent error icon () next to the Manual Trigger should disappear , indicating that n8n recognizes the workflow as being in a valid, error-free state.
However, the actual problem I’m facing is that I cannot perform this activation action at all .
When I click the “Inactive” toggle, the “No Entry” sign () appears , explicitly blocking the action.
The switch visually remains “Inactive” .
The error icon () persists .
So, while activating a manual-trigger workflow doesn’t change its runtime behavior (it still needs manual initiation), the inability to even toggle it to the “Active” state , accompanied by the blocking symbol () and the persistent error icon (), indicates a more fundamental issue. It seems n8n is preventing the workflow from reaching what it considers a valid ‘active/ready’ state, even though the workflow itself runs correctly in tests and has no triggers that require activation according to the tooltip.
I hope this clarifies the problem. I’m trying to understand why n8n is blocking the activation (showing the symbol) for such a basic workflow configuration.
I am not sure if I got what would you be able to achieve you cannot achieve now by changing all those things, in terms of n8n principal functionality (i.e. the main purpose of n8n regarding workflows execution)?
What are the new capabilities would unveil in doing so?
I would consider it really confusing if in a list of workflows I’d see fully manual workflows marked as activated. It is kind of “oh, this workflow can be triggered by an external event? hmmm, but it is not supposed to”. Also, any workflow is ready for execution at any time (unless it doesn’t have any trigger nodes at all). Indication of this would be redundant.
Or is it about a UX that confuses you?
As for the “indicating that n8n recognizes the workflow as being in a valid, error-free state”, I am not convinced this is a really good idea. Error-free indication is something completely different from readiness to execute a workflow. To me, the errors indications are more valid, because error-free indication can be very misleading. You’d need to actualy execute the workflow every other [milli]second to make sure the error-free state is still valid. I will give you an example: your access token may expire a second after successful execution of a workflow, a remote service API may change the next second, the request quota may be exceeded after another second, a remote service may be down after another second. Just recombine those factors. So an explicit error-free indication can be very misleading. Oh, and it can become “error-free” the next second. We can vaguely assume the workflow is error free if there is no errors indications after a test execution or in executions inspection tab.
I am trying to understand what the problem is. Problem as in “something is blocking us from doing meaningful things”.
Thanks for your detailed perspective. I understand your point that activating a purely manual workflow might seem confusing semantically, as it won’t run automatically, and that a static “error-free” indicator has limitations.
However, the core problem I’m facing isn’t about the expectation of automatic execution. It’s about these specific, abnormal, and blocking UI behaviors that prevent me from getting the workflow into what n8n’s own UI seems to consider a valid, ready state:
The Blocking Action: When I click the “Inactive” toggle, I get the “No Entry” symbol () . The system is actively preventing me from changing the toggle state. This isn’t just about semantics; it’s an action being blocked.
The Persistent Error Icon: Despite successful test runs (“Test workflow”) and the tooltip correctly stating “This workflow has no trigger nodes that require activation”, the error icon () remains next to the Manual Trigger. This suggests n8n itself still perceives an error or invalid state, contradicting the test results and the tooltip. Clicking this icon also leads to the “Test workflow” button, which is not the expected behavior for an error indicator.
What is being blocked from doing meaningful things?
The ability to clear this persistent, and likely incorrect, error state () flagged by n8n’s UI.
The ability for the UI to accurately reflect that the workflow, as configured, is ready for manual execution without apparent configuration errors (i.e., removing the and the block). Right now, the UI tells me there’s an error and blocks me from changing the state, even though tests run fine.
I agree that error indications are more valuable than a potentially misleading “error-free” status. My issue is that I have a persistent error indication () that seems incorrect, and the system () prevents me from acknowledging or clearing it by toggling the state.
This is also happening in the context of another potential state-saving issue I reported to support regarding the Facebook Webhook URL not saving correctly, which makes me suspect a broader issue with my instance’s ability to handle state changes or configuration saving.
So, the problem isn’t the meaning of “Active” for a manual workflow, but the inability to clear a persistent error flag () and overcome the explicit block () on changing the workflow’s state.
I personally, do not see any value in possibility to make or mark workflows that can only be executed mnaually as “active”. Any workflow is “ready” for manual execution, whether it allows external triggering events or not.
I do see value in distiguishing if a workflow is ready to react to external events or on schedule, thus consuming my executions quota and using active (i.e. externally triggerable) workflow quota, i.e. current UI/UX provided.
If I understand you correctly, you are wondering why you can’t set your workflow to active(?)
N8N doesn’t allow you to set a workflow to active if you only have a manual trigger.
I believe the idea is that the workflow will never run because there’s nothing outside the workflow that would ever trigger it.
You could add (or replace) a trigger like Schedule and set the params to something like once every 10 years if you don’t want it to actually run but still be active.
Thanks for your input and the suggestion about the dummy Schedule trigger.
I understand that a manual-only workflow doesn’t run automatically when “Active”.
However, the UI behavior is confusing. The tooltip explicitly says “This workflow has no trigger nodes that require activation”, which seems to contradict the idea that activation is intentionally blocked because it’s manual-only.
More importantly, this doesn’t explain the persistent error icon () on the Manual Trigger, nor the blocking symbol () that appears when trying to toggle the switch. These UI elements suggest something is actively wrong or blocked, beyond just the workflow being manual.
While the dummy trigger might be a workaround to force an “Active” state, my main goal is to understand why the UI is showing an error () and blocking the action () in the first place for a workflow that tests successfully.
Is this persistent error icon () and the blocking symbol () expected behavior for manual-only workflows, even when the tooltip says no activation is required?
Adding to this, I’m also facing a persistent issue with configuring the Facebook Webhook trigger in another workflow. No matter how many times I save the Production URL , it keeps reverting back to the Test URL upon reopening the node or refreshing.
It is not possible to save the Trihger URL (at least not the field “Test URL” or “Production URL”) as this field is read only and just shows you the URL.

) appears, indicating that the action is blocked.
