I have a Power Automate run that is triggered in PowerApps and copies values from various input fields into a SharePoint list as a Submit function. I have several ComboBoxes that are working correct, but those all have a required field that must be inputted. One of the ComboBoxes does not have a field requirement, so it is often blank and it triggers the error "The Method "Run" has an invalid value for parameter 'varDisposition_value'.
Here is the input expression for varDisposition_value:
If(IsBlank(ComboBoxDispositionUpdate.Selected.Title) || IsEmpty(ComboBoxDispositionUpdate), varRecord.DispositionUpdate, ComboBoxDispositionUpdate.Selected.Title)
varRecord.DispositionUpdate is a value that is pulled from the Gallery as the Item may (or may not) already have populated data iin the various fields. This function is testing for IsBlank/IsEmpty conditions in the ComboBox, and returning any value in the varRecord variable if the ComboBox in Blank/Empty. If it's not Blank/Empty, I'm writing the value to the sharepoint list. This exact expression works for all other ComboBoxes, but they also have values.
Is there a way to run this submit function to allow for empty/blank fields in a combobox?
Hi @remariu,
Have you solved your problem?
Do you want to submit blank value using a flow?
Could you please tell me how you configure the flow?
Actually, the flow surely does not support to transform blank value.
As an alternative solution, you could consider adding an action like Update item and assign the null value to the corresponding column.
