Hi @Anonymous,
Could you please share a screenshot of your flow's configuration?
Could you please share more details about your SharePoint list?
Further, is it the WLA column a Person or Group type column?
The error message told that there is something wrong with the formula that you provided within your "Update item" action, the Claims property could not be selected based on the formula that you provided.
I have made a test and the issue is confirmed on my side. I assume that the WLA column is a Person or Group type column in your SharePoint list, if the WLA column is empty, when you use the "Get item" action to get the correspodning item, the WLA column would return empty. In other words, if the WLA column is empty, the Approver Claims dynamic content would not be shown up within the result of the "Get item" action.
In addition, you could consider take a try to add a Condition to check if the WLA column (Person column) is empty before the "Update item" action within your flow. I have made a test on my side and please take a try with the following workaround:
Within Condition 2 box, click "Edit in advanced mode", type the following formula:
@or(empty(body('Get_item')?['Approver']))
Within Condition 3 box, click "Edit in advanced mode", type the following formula:
@empty(body('Get_item')?['Executor'])
Within Condition 4 box, click "Edit in advanced mode", type the following formula:
@empty(body('Get_item')?['Executor'])
Note: The Executor column and the Approver column are both Person or Group type columns in my SharePoint list.
Best regards,
Kris
