Hi All.
I've had a flow in place for a while to copy form submissions to SharePoint, the form contains a number of date picker fields which copy to date fields in the list. Not all of the date fields will be populated depending on what the end user enters.
Everything worked fine up until I made a minor change to the form to add a multiple-choice question and updated the flow accordingly (no change to any date questions either within the form or flow) but now the flow is constantly failing as, I'm going to make an assumption from the following output, there are date fields in the form with 'Null' value:
The 'inputs.parameters' of workflow operation 'Create_item' of type 'OpenApiConnection' is not valid. Error details: Input parameter 'item/AD_x002d_ShiftDate' is required to be of type 'String/date'. The runtime value '""' to be converted doesn't have the expected format 'String/date'.
I don't understand why this flow, when I made not changes to the date fields has suddenly stopped working due to the other date fields being null.
I'm guessing I need to insert an expression to make it 'OK' for the field to be null but I don't know what I'm doing with expressions so any help would be appreciated.
