Describe the problem/error/question
When I run a workflow that uses the GMail API from the Editor it works perfectly. Now I need to run the workflow from another workflow, which I am doing via a webhook call. That fails, with the error being “precondition check failed” which has been mentioned by many others here.
I’ve checked running the workflow with the exact same input parameters via the Editor as was called from the other workflow.
Is there some difference in how the Credentials module is being used when in the Editor vs when workflow being called from another place?
What is the error message (if any)?
400 precondition check failed
