Unable to update custom fields in ICM

[ShivaniSaha]

Hello all,

I am trying to automate the creation of ICM incidents through Power Automate. I have used the 'Create or Update ICM' action and trying to update some team specific custom fields. These fields were configured specifically for our team.

When the flow is run, ICM gets created and assigned to our team. But the custom fields are not getting updated.

It is giving error, mentioning Reason: Custom Field Key was not found.

I tried using both Container types - Tenant and Frontend but nothing worked.

Can someone please help resolve this issue.
