Failed to deactivate trigger of workflow ID "xxxxx": "Called end on pool more than once"

[Pablo_Muniz]

Describe the problem/error/question

My workflow has stopped working and I cannot edit or delete it. Every time I try to do any of these tasks I get an error " Failed to deactivate trigger of workflow ID “YKiEFk7zHk3wNht9”: “Called end on pool more than once”

What is the error message (if any)?

Hi @Pablo_Muniz, there is no need to reach out through multiple different channels. Following your email report our engineering team has published a fix hopefully adressing the problem:

fix(Postgres Node): Close connection pool only if it's not already closed or closing

This available in n8n 1.30.0, you can upgrade through the n8n cloud admin panel.
