Hi

I have an automated flow from Customer Voice Form to Dataverse that works if a date is selected in the Form field 'Renewal Date', but if it is left blank the flow errors with the following:

 

The 'inputs.parameters' of workflow operation 'Add_a_new_row' of type 'OpenApiConnection' is not valid. Error details: Input parameter 'item/renewaldate' is required to be of type 'String/date-time'. The runtime value '""' to be converted doesn't have the expected format 'String/date-time

With many thanks

    Hi @Xch21 

     

    Pls try using if() function to check for empty or blank value in form field:

    if(empty(<dynamic value of renewal date>),null,<dynamic value of renewal date>)

     

     

     

    If this helps & solves your problem, please remember to give a 👍 and accept my solution as it will help others in the future.
