Unable to Use Flow with Custom connector in Power Apps (Collection is blank/shows nothing at all)



So I am trying to use a flow that I created with a custom connector, a Parse JSON Step and a Response Step in PowerApps. I am able to test each step in the flow and can confirm that the output at each stage and the final output work exactly as expected. However I only get the column names with no data whenever I try to use the flow in a collection.


If I remove the Parse JSON step from the flow, I am able to see the whole JSON as a text object whenever I try to use it in a gallery. Is there anything I am missing here?

Hi RashidMercana,


Taking JSON-formatted data from a flow and putting that into a Power Apps collection can definitely be tricky.  In the past, I have had success referencing the steps laid out in this blog from a few years ago:


It's written with a SQL data source in mind but the same principles should apply to other data sources.


I hope this helps!
