Hii,
I am Getting the error during execute the Gmail node.

Please give me the solution anyone!

Hi @Pushpendra_Yadav, can you share your workflow so folks can reproduce the problem and see how you have configured your Gmail node? You can of course redact any confidential values, but it’d be good if the data structure itself remains the same.

Also, can you confirm which version of n8n you are using?

FYI Google credentials are set with service auth without Impersonate a User

@MutedJam I have verified that I can use the service account credentials to impersonate a user for Google Sheets as shown in this tutorial. Note though that the credentials user interface still gives an error message (but they work!) which is described in this github issue (2397). However my original problem persists, since I want to use Gmail API, and here I still get an error even if I just “ignore” the error in the credentials UI.
