Re: Error opening file: Cannot read property 'connectionInstanceId' of null

Hello there,

 

i'm having the same issue since a few days. My App can't be edited any longer with the same error message being shown. I do have a flow connected to the app, however it is deactivated. Setting the flow active or restoring a previous version did not solve my issue. Web editing shows the same error message.

Thanks for the support!

I have the same issue. Was looking for hours to find a solution.

 

Hope you can make it work ASAP. 

I'm already thinkging if it was a good idea to use PowerApps, it just seems to be in baby shoes still.

Same here.

 

This is incredibly frustrating. I've had an app ready to go for 4 months that has worked fine, and the first day we went to put in into operation this error pops up! They can't just revert to before the update??

We are still working on the hotfix. Should take another 3 -4 hours.

I just clicked on "Approve" for the deployment, the web version is on its way. Should be live worldwide in an hour or two.

I'm having the exact same problem.  This is what I did before things went south.

 

1) Edited PowerApp flow on flow.microsoft.com (added new parameter to be given by PowerApp)

2) Open PowerApp in PowerApp Studio (Windows)

3) Tried to modified previous flow (original had one parameter) with edited flow

4) PowerApp Studio did not recognize edited flow (still thinks it receives only 1 parameter)

5) Deleted flow from PowerApp app

6) Closed PowerApp app and opened it again in Player

7) While player was loading, selected edit on the upper right corner

😎 Received the "Cannot read property..." error

 

The only "fix" was to restore to a previous version that did not implemented the modified PowerApp flows

 

Deleting/Disabling/Recreate flows did not work
