Getting a response from Power Automate to PowerApps

Hi,

I am trying to get a response from a Power Automate flow to PowerApps.

I have a label in PowerApps that should appear once the flow has successfully run.

I’ve set the Visible property of the label to variable varLabelVisible. The variable value should be set to true by the workflow, once successfully run, therefore making the label visible.

A button triggers the flow. Its OnSelect property is set to:

Set(varLabelVisible,Flow.Run(…))

The flow runs successfully, giving the following output for the Respond to a PowerApp or flow action:

{

"varLabelVisibleValue": "True"

}

however, it doesn't seem to trigger the desired action in PowerApps, as the label does not appear at the end of the flow run.

I suspect I might have grossly misunderstood how the Respond to a PowerApp or flow action is supposed to work and what is the correct syntax to be used in PowerApps to retrieve the value from the flow.

Thank you for your help!

The flow response will always be a JSON object, even when you're just passing one value.

For your flow call, changing it to

Set(varLabelVisible,Flow.Run(…).varLabelVisibleValue)

should fix this.

Make sure the output of the flow is really a boolean, since that what your app expects. It looks like a text value now, I'd expect true instead of "True".

Hi @shoog , thank you for your reply! I will give it a try. In the meantime, here is how I set up the output in the flow:

Does it look correct?

Thank you

Hi @Gilmour ,

The returned value is of type Text, rather than Boolean. You can try below in Visible instead:

varLabelVisible.'work completed' = "True"

Best regards

Better change the response to a Yes/No value or modify the code a bit to convert the datatype in your app:

Set(varLabelVisible,Flow.Run(…).varLabelVisibleValue = "True")

This way the varLabelVisible in PowerApps will be a boolean, while you don't have to change the datatype in your flow.

Thank you so much @shoog ! Unfortunately I met another snag... The statement gives me an error, because the Flow.Run has over 50 levels of nesting (it's a very long series of inputs). So I'll have to break up the flow to be able to test your code... Will give it a try! Thank you again!
