I made a flow based on what i have learn I was using my gmail with no problem been able to read all new incoming message and sundenly I was not able to do it more. What is weird is that for sending it works.
Welcome to the forum. I’ll take a look at this to try to help you.
So that i have a little more info, can you expand the “other info” in the error message in your screenshot and share it? sometimes that tells us exactly what the issue is
Also, please embed your workflow into the forum so we can look at it, do that like this:
Please note that this issue is only happening on the ‘Gmail Trigger Node’ as all other Google nodes seems to be functioning. For context, my workflow is a single Gmail Trigger Node.

Correct - this happens every time I add a gmail trigger node, existing workflows and new workflows. Confirming that the webhook url matches my instances url with https://
It seems to be an error in the polling logic under the hood. So sometimes just resetting the node or rebooting it could clear an issue like that, so it could seem intermittent
Issue still persists, even with new workflow, credentials, and instance restart. Very strange how this issue only occurs on the ‘Gmail Trigger Node’ (Gmail action nodes work fine).
It is not very weird because the error is coming from the code related to the trigger node’s polling, which essentially is the process of Gmail checking for new messages.
I tested on both 1.56.2 and 1.74.3 and couldnt reproduce the error.
Its possible that the connection with google is bad. check to make sure your connection is set up right and that gmail has all of the scopes it needs
Has anyone made any progress with this? I am having the exact same issue.
I have tried adding the trigger on a fresh node. Same issue. Also tried restarting the service, same issue.
Other gmail nodes are fine. Tested sending out emails, no problem.
I am running Self Hosted on Render.
Here is my error code:
{
“errorMessage”: “Cannot read properties of undefined (reading ‘includes’)”,
“errorDetails”: {},
