AI Builder error when reloading app



I'm trying to use the new AI Builder functionality in PowerApps (object detection).


As a PowerApps Plan 1 and O365 E1 user and tenant admin, this is what I've done:

  • I added a new CDS entity called Cars, with 2 fields Brand and Type.
    I provided sample data.
  • I created a new AI Model called Cars as well, and used the field Brand.
    I uploaded about 64 images of 4 different car brands, trained the model and published it. 
    Testing the model works perfectly!
  • I created a new PowerApps, added the Object detector to a screen, linked it to the Cars AI model.
    When running the app (uploading an image) this works flawlessly.
  • Here is where it gets weird: when I Save and close the app and then re-open it again, I get an error Couldn't load AI Builder model.
  • When I click on Detect and upload an image it gets worse => the whole app AND studio go blank with the red error Something happened. Try again later:

This behaviour is the same when running the app on an Android phone.


I verified that my account has the Commom Data Service User Security-role:


Strange thing is: when I delete the control and re-add it: I can select the AI model just fine and everything works again.
But when i save and re-open the app the errors reappear again :'(


Can anyone from the PowerApps team help me in the right direction to solve this error?

Re: AI Builder error when reloading app

Hi @nvanbutselcxndm ,


Are you using the app on web browser? If so, please check with another browser and on mobile phone to have a test.

Have you tested with another app? 

If this issue is specific to this app, what is the session ID?

Anyone else having issues with the new AI Builder components?

The scan-a-contactcard component works perfectly, but the ones that rely on an AI-model give problems.


Re: AI Builder error when reloading app

Hello @nvanbutselcxndm 


Are you still seeing the error?

AI Builder Object Detector component is still in preview and we're always bringing improvement in this new component.


If you're still facing the error on your app, can you try to create a new blank app with only an Object Detector component and retry your scenario, please?


If your app is somehow out of ordinary, can you please describe it in order for us to improve the compatibility of our components?


Thank you for using AI Builder,
