Hello everyone,

short description:
I have a flow. This uses the trigger on form submission. In the form survey there is a field where you can enter the date, but you don't have to (form function date input). I have now entered the “if-empty” expression that if no date has been entered in Forms, the field should remain empty in the SharePoint list. The corresponding field is also a date element in the SharePoint list. Unfortunately, I always get the following error:

“The ‘inputs.parameters’ of workflow operation ‘Update_item_10’ of type ‘OpenApiConnection’ is not valid. Error details: Input parameter 'item/purchase date' is required to be of type 'String/date'. The runtime value '“”' to be converted doesn't have the expected format 'String/date'.”

The printout below as a screenshot. What am I doing wrong or what would be the correct expression?

Thanks for your help and best regards
