Zoho Flow - Jira Update issue problem

Zoho Flow - Jira Update issue problem

Hey community !

I am trying to make a flow with Jira / Update issue but each time I try to turn ON my flow, I get the error : Jira Cloud says "null"

My connection is working just fine when I test it. I also revoke the Jira token and assigned a new one (Just in case).

I am using the same Jira Connection with another Flow that works just fine.

Anyone got the same issue ?

** I don't have any logs in the history as the Flow won't even turn ON **
