  • Can you please go back to a failed run of your flow and click the "Update Item" step inside "Yes". That should provide more information about why that step is failing.

Referring to https://learn.microsoft.com/en-us/azure/logic-apps/workflow-definition-language-functions-reference#empty, empty function can't be used on types other than String, Array, or Object. Though numbers are typed as Float, Integer or any number types which is also an object in dotnet, the term "Object" here refers to an entirely JSON object. So, that's probably the reason why it's error.

So you might need to change your expression to if(equals(items('Apply_to_each')?['Noofassignments'],null),1,add(items('Apply_to_each')?['Noofassignments'],1)).

Hope that helps.
