Invalid number of arguments

Hi everyone,

I am facing an issue with triggering the Power Automate flow via Power Apps.

My flow functions to create items in a SP list and it uses 16 inputs with 5 required and the rest optional.

I structured it like this because depending on the input for 1 of the required fields, additional info will be needed to create the item. When I tried running coding it into the PowerApps, I received an error where it receives 16 arguments but expects 5-6.

Is there a way to make it increase the expectation limit to match the number of inputs without making the inputs required?

Hi @RickyT ,

Since all 16 values are from your App, in your flow you will use dynamic contents from PowerApps trigger 16 times, that's why you need 16 input fields required to trigger the flow.

You can validate inputs in your App with 11 If statements, when they are non-required fields and don't need values, set input fields with Blank().

Best regards,
