I use Zapier to send filtered emails from Gmail and create channel messages in Slack. However, some of my Zaps have recently started failing with the following error:
“Failed to create a message in Slack. Error while hydrating data from Slack: Cannot convert undefined or null to object.”
These Zaps have been running normally for a long time but recently started failing and are even being automatically turned off by Zapier. I’m not sure what changed. However, when I test the Zap, messages still seem to be created in Slack, despite the error message appearing.
Does anyone have insights on what might be causing this or how to resolve it?
