Power automate respond to a power app variable type issue!

Posted on by FettlinTyke

Hello,

I have created a form which sends various variables to a power automate flow, it creates a SharePoint file, and, using 'Respond to a power app or flow' it returns 3 text values, lets call them text1, text2, text3. The power automate flow works and looking at the outputs of the flow, the correct information is returned.

In power apps I call is using:

Set(varResponse, CreateNewDoc.Run(

var1.Text,

etc

)

I then want to set a variable to one of the outputs using Set(test1, varResponse.text1). This throws a warning: The '.' operator cannot be used on Boolean values.

When checking the power apps variables, varResponse (Boolean: Blank) so it believes I am returning nothing.

This was working fine but then suddenly broke during a test run when I was inputting values, nothing to do with changing any code.

I have tried various fixes suggested by Copilot (yeah, I know) but the latest was:

Deleting the power automate linked flow in power apps, commenting out all mentions of the variable, exiting both power apps/powerautomate, clearing my browser cache, then restarting the computer, updating the power apps flow link to reconnect my flow then just commenting in the Set(varResponse, CreateNewDoc.Run(...) and the variable varResponse automatically reappears as a Boolean:Blank again. When I tried to run the flow (to see if it needs to run to set the variables values) the raw outputs of the respond to a power app or flow is:

{
    "statusCode": "200",
    "schema": {
        "type": "object",
        "properties": {
            "idn": {
                "title": "text1",
                "type": "string",
                "x-ms-content-hint": "TEXT",
                "x-ms-dynamically-added": true
            },
            "idlink": {
                "title": "text2",
                "type": "string",
                "x-ms-content-hint": "TEXT",
                "x-ms-dynamically-added": true
            },
            "filename": {
                "title": "text3",
                "type": "string",
                "x-ms-content-hint": "TEXT",
                "x-ms-dynamically-added": true
            }
        },
        "additionalProperties": {}
    },
    "body": {
        "text1": "Correct String",
        "text2": "https://correct URL",
        "text3": "File 1036.docx"
    }
}
This is the same as a run when it was working as intended.
 
In power apps, varResponse is not Boolean: true. varResponse in my current code is only used in the Set(varResponse, CreateNewDoc.Run(...) and when I comment this out, the varResponse variable disappears from the global variable list which shows it is not being set anywhere else.
 
Has anyone got any suggestions? I have been wasting over 2 hours on this so far and it does not appear to make sense!

Did you try to go to Flows in your App and remove the flow than ad it again? sometimes when you doing some changes or Save flow in PA they desynchronise showing errors.

@SebS Yep, in the last section I explained I had removed the flow, and even cleared my cache and restarted my computer as just removing it didn't work.

Sorry, the formatting on my post went off but Microsoft prevent highlighting all text in mobile version so I can't update it all so it is clearer.

Look like contractual error but wierd but I do not know how your full code looks like and how You designed your power automate flow

it should have Respons Action

Then you could do something like this to catch it

Set(varResponse, CreateNewDoc.Run(var1.Text, ...));
Set(test1, Text(varResponse.fileId));
Set(test2, Text(varResponse.fileLink));
Set(test3, Text(varResponse.fileName));

but you need to have output parameters and staff

Well colour me embarrased. I appear to have deleted the wrong bracket when moving some other code so my code was:

Set(varResponse, CreateNewDoc.Run(

"Text 1"

etc.

)

<other code that should not be here>

); <<<<closed the original Set code block after the other code.

Thanks for your help @SebS, confirming my code was the same as yours was what showed me the error.

Refresh the Power Automate flow within the Power App and get the response data using varResponse.ResponseFieldName. Bind this value to a label’s Text property for testing purposes. Once validated, the variable can be used wherever required within the application.
