Gmail node getting triggered multiple times for same email

Hey Team, I am using the Gmail Trigger node as a trigger for my workflow. I have set the poll time for the node to every minute. There have been multiple instances where the Gmail node triggers the same workflow multiple times. Is this a bug in N8N, or do I need to update some configuration in the Gmail node? No error message Please share the workflow Note - I have removed client id and client secret from the Gmail Node. Information on your n8n setup [email protected] - R…

As per the last comment from Jon, This issue happens for selective emails. And I can see a pattern in them. But still I am not sure if this is the cause.

I can see that this issue happens for mails when the label “UNREAD” is not in the list of labels in the json inside Gmail trigger node. I can observe this for 10 instances from the morning.

However I am not sure why a new email will not have a UNREAD tag. May be a bug from gmail api or downtime during the poll.

I believe “Unread” label must be applied by default for all the poll in n8n. Please let me know your thoughts. If you do not include Labels filter in the Gmail trigger node and send email to the connected gmail account continuously, say 1 email per minute to test, this issue can be reproduced.
