Workflow can't be published due to 402 bug error

Problem activating workflow
The following error occurred on workflow activation:
There was a problem activating the workflow: "Status code 402"Describe the problem/error/question

Workflow could not be published:
There was a problem activating the workflow: “Status code 402”

What is the error message (if any)?

Please share your workflow

https://thecodingcompany.app.n8n.cloud/workflow/Fz7nIyjjb7imILzG

Share the output returned by the last node

I can run all input → output individually but I can not publish my workflow because of the error.

I had this before and I cancelled my subscription. Now I re-activate my workspace, removed the workflow, restored a backup and still nothing works.

Information on your n8n setup

hello @Victor_Angelier_BSc

Please, share the workflow.

You can select all nodes with Ctrl+A and copy them with Ctrl+C. Then, past the content after pressing the button </> with Ctrl+V.

And show a screenshot of the error.

WF is too big for importing. Does it contain any red exclamation marks?
like that:

No it does not have any red exclamation marks. I can run everything manually, no problem at all. It just don’t want to publish it. Wierd thing is, in the beginnen it ran perfectly fine!

Can’t say what the reason is. Try splitting the WF into smaller workflows (use Execute Workflow & Execute Workflow Trigger nodes for interconnection), then it may be clearer which part is not working
