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

Hello,

 

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?

 

Thanks,

If you could provide an expanded screenshot of your Flow and steps, your Flow run history, and of any detailed error messages you're receiving we could likely better assist you. Also, for the best results, you may want to review How to write a good forum post.

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: https://powerapps.microsoft.com/en-us/blog/return-an-array-from-flow-to-powerapps-response-method/

 

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

 

I hope this helps!

Tom
