PowerApps does not receive the data response from Power Automate

Posted on by daniel88

Hi,

I build PowerApps, which will call a flow, when the flow got the result, the flow will respond PowerApps as following picture

However, I found that even my flow is run correctly, the PowerApps is unable to get any data from this Flow.

The following picture shows the response to PowerApps

But in PowerApps, even I run the flow multiple times:

Set(testresult, myflow.Run());

The result of those values are Blank() but not any valid values or text

Can anyone provide me solutions for this? I do everything I can think to get the result of the flow, but the PowerApps itself seems not work as it should...

In my experience, the reference to the field in the testresult record does not use single quotation marks. Have you tried testresult.1 or testresult.2? You can also inspect the testresult record in the Variables menu choice in the development environment to explore the record structure.

Hope that helps,

Bryan

Thanks for your reply, but I tested to use testresult.1, which shows

Also, the value of testresult is Blank(), which seems telling me no data is stored in testresult after running the flow by this code:
Set(testresult, myflow.Run());

OK, next thing to try is to disconnect and reconnect the flow from your app. This will force the Power Apps service to re-read the flow schema and re-establish the connection.

Thanks for you reply. I tried the following:

1. Remove the flow and add back same flow to PowerApps.
2. Remove the flow, save and quit PowerApps, open the PowerApps and add back same flow.
3. Changing the flow by: Remove the respond and trigger of the flow, add them back again.
4. Reconstruct the entire flow with a different name, remove the old flow, add the new flow.
5. Add a new flow, then remove the old flow
6. Changing types of output of the flow
7. Changing the output of flow as constant string like "OK"

All of the above method does not receive data from flow.

I believe my flow is work is because I made another PowerApps before, and it can get back the result from exactly same flow. And yesterday I checked my old PowerApps, PowerApps no longer able to receive the data from the flow.

OK, thanks for sharing your efforts and results - that eliminates a lot of my questions. One last one though: Are you using the original or the V2 Power Apps connector in the flow? The V2 connector works smoother in my experience, so consider changing to that if you haven't already.

Also, were you able to inspect the testresult record in the View-Variables section of make.powerapps.com? It would be valuable to see if anything at all ended up in that record.

Thank you for your reply, I am using PowerApps V2 as trigger of the flow, which is the one that I can select input fields and types in trigger.
Inside the View-Variables section, I was able to see the fields like "0", "1", "2" ... in the testresult. However, all of them does not have a value below it. All of the fields inside this record is empty. I also tried to assign values by code similar to Set(testresult,{'0':1,'1':1,'2':1,...}); manually, and the manual assigned values is working. So, it seems like Power Automate does not return value to PowerApps.

Any idea about how to fix this problem?

If you have tried all the steps we mentioned earlier, then you need to start a support ticket with Microsoft

Hi, in case it helps, I was experiencing exactly the same issue.

It turns out my Power Automate flow was returning an Integer, but it seems PowerApps can only process responses as string.

I had a similar issue where a flow stopped responding and had to replace the respond to a PowerApp or Flow (in the flow) to get it working again.
