I have this instant Power automate flow, which accept 5 parameters:-

Now when i try to call this flow from my Canvas App, as follow:-

ExportItems.Run("SPI",
varQueryTrimmedSPI
,User().Email,"1","2");
 
But i got this error:-
 
Invalid number of arguments: received 5, expected 3-4.
 
As follow:-
 
so why i am getting this error, although the power automate has 5 parameters and not 3 or 4..

Make sure you Refresh the Flow inside the Power App. This is usually caused by adding additional parameters to the flow and then saving it without refreshing the reference in the Power App.

I also remove the last parameter, now i am even getting error on the fourth parameter (which use to work well, before i added the fifth paramter), "Expect a record value instead".. i am not sure why it is expecting a record value for the fourth parameter although it is a string parameter???

What does the string in VarQueryTrimmedSPI Look like? Is it possible that some punctuation in that is being misread when you pass it?

And is the 4th parameter marked as optional? If its set to be optional then you need to input it in the form of a record. Something like this

{text4: "string to submit"}

Can you provide a screenshot of what you mean that the checkbox is not selectable?

@Pstork1

Thanks for the reply, i mean this checkbox is unselectable, as-if it is disabled,, so i mean that i can not make a paramter as optional..

any way i were able to fix this issue, by removing the new parameter, remove the flow from power app, save the power app, re-add the parameter, re-add the flow inside power app, wait fro 1 hour,, and the problem got fixed... I am not sure what caused this problem and what cause it to get fixed... this is another confusion point raised by power platform.. without any leasson learned..

To be clear, it is a bit confusing. But when you select that checkbox it stays checked but the label next to it changes from "Make the field Optional" to "Make the Field Required". But the checkbox remains checked for both prompts.

@Pstork1

Things can not be more confusing,, so if the parameter is changed to optional then i will need to pass it as a record instead of as a string?

;If it is marked as optional you can still pass a regular value like any other parameter. But if you want to leave it null then you have to pass it as a record with the parameter name and a null value. You can't not pass a value. Optional just gives you a way to pass a null value.
