The issue was found in the 23.1.2 cloud  version 

When M45, control type C47 is entered and saved, and then once gone to details the error comes when trying to enter a new record and selecting work center.

Same with M55,control type C47

PostingControlDetails/Form (server error)
Error while serializing contents.

This error happens when the server cannot serialize the data to be sent to the client.
A common cause is that one attribute's length exceeds the defined maxlength in the projection.
To find more info, open Log Window or Debug Console, refresh and then check Network Tab in DevTools. In the response there can be more detailed information about the exception.
Error details: N/A

Has anyone encountered this issue before? and is there a workaround for this?

 I have reported to IFS as well.

Thank you
