Sending JSON from Power Apps to Flow works in debug, lost with published app

(0) ShareShare
ReportReport
Posted on by Microsoft Employee

I built an app that sends a JSON string from Power Apps to Flow, this works great in debug - I can see and manipulate the json with flow.

 

However, once I publish, the published app sends everything except the JSON package. it arrives as [{}] according to flow.

 

The outputs from the "Power Apps" header is

    "body": {
        "Initializevariable_Value""[{}]",
 
Vs when I am in debug, I get a full json string that I can parse and use with Flow. 
 
How can I debug this more? It appears to be Power Apps not sending the string.

    Hi @PeterInWa,

     

    Could you please share your Flow configuration? It seems that you have some issue when you pass json from Power Apps to Flow, there is a blog could tell you how to do it, hope it helps you:

    Send a Collection from Power Apps to Flow (powerobjects.com)

    Thank you,

     

    I found I was using 'clearcollect' on load AND on selection - so when I selected items, I cleared the table used to create the JSON package. So once I changed the select to 'collect' the table remained and the contents for the JSON package were intact and able to send to Flow.

    Hi @PeterInWa,

     

    OK, clearcollect will empty all values. If your problem has been solved, You could go ahead and mark the post as solved by clicking “Accept as Solution” so that this thread will be marked for other users to easily identify!
