Hi everyone,
I have a Power Automate workflow using the SharePoint trigger "When an item is created or modified" that works perfectly on my DEV environment but fails on PROD with the following error:
The API 'sharepointonline' returned an invalid response for workflow operation
'When_an_item_is_created_or_modified' of type 'OpenApiConnection'.
Error details: 'The API operation 'GetOnUpdatedItems' requires the property
'body/value/0/zzz' to be of type 'Object' but is of type 'Null'.'

Details:

I have Sharepoint 2016 on Prem.

"zzz" is a mandatory multi-value Person field - it is always populated
Both DEV and PROD lists have the same column configuration (multi-value Person field, required, People Only)
The PROD list has approximately 25 columns - not unusually large
Tested with both "When an item is created" and "When an item is created or modified" triggers on PROD - both fail
The error occurs even on newly created items where "Requested By" is populated

Question:

Why does the trigger work on DEV but not PROD with identical column configuration? Is there a way to exclude a specific column from the trigger schema validation without using views? What can I do to make that trigger work?
Any help is appreciated.

Thank you!
