I have a powerapp it is a form that connects to list.

When I press submit it sends to list AS WELL AS starts a power automate flow which populates a word document.

Using this at a basic level onselect

FLOWNAME.Run(DataCardValue140.Text)
 
Normally works fine. 
 
Now for some reason is the DataCardValue is prepopulated (i.e. app user is not entering information) it works. 
BUT if information is added it keeps saying the below 
 
FLOWNAME.Run failed: The function 'Run' has an invalid value for parameter 'text' - a blank value was passed to it where it was not expected. Please make sure that a valid argument is passed to the function
 
If I grab another text box and set it's text property to the datacardvalue.text and then use that text box in the FLOWNAME.Run(textbox.text) it WORKS 
 
But this is so long! I don't understand why it does not seem to be recognising text when entered normally??
 
The list enters text just fine 
The list all have single line of text 
It worked fine before 
it is driving me NUTS

Could you try to put the DatacardValue140.Text into a Label just to be sure that everything is as you expect it.

Yes I have tried this and it all comes through as expected.

And when I use that label to run the flow it works.

But this is just so much to do and more error prone

Okay yes I get that, it was just to be sure that there wasn't something changing the input inbetween.

Could you try And change in Power automate that it is not required and test it once? That way we can see what Power automate recives
