Errors after renaming PowerApp ('connectioninstanceId' of null, UserInterventionNeeded_StorageLost)

Posted on by Community Power Pla... Microsoft Employee

Hi All

I have a PowerApps project in progress (I am the owner of the app) and today I can no longer open it in design view.

Our organisation is running O365 with SharePoint online. We have no desktop Windows Studio version of PowerApps, only the online 'Edit on the Web' design option.

The following error messages suggest that it's an AAD issue. If I run the app (i.e. not open it in design) then it works as required however I suspect this is a cache of the last good build which remains on the (Azure?) service.

Symptoms are as follows;

Chrome/Edge:
Error message - "powerapps cannot read property 'connectioninstanceId' of null"

IE11:
Error message - "Hmmm ... We couldn’t sign you in." with the following log;

UserInterventionNeeded_StorageLost

Transient storage was lost after navigating to AAD login. This can happen in IE and Edge if Trust Zones are misconfigured.

BeforeAadLoginTimestamp:
NumAttempts:
Error: UserInterventionNeeded_StorageLost
ErrorDescription: Transient storage was lost after navigating to AAD login. This can happen in IE and Edge if Trust Zones are misconfigured.

[INFO] [2017-05-29T05:08:48.915Z] Came back from AAD login

I tried to roll back to earlier versions but I get the same problem. I suspect that renaming the app had something to do with the error.

Note that I can open any other app whether created by myself or others so it's unlikely to be an issue with my account OR the trusted connection settings on my browsers.

I can partially open the app in design view from the File|Open menu in PowerApps Web Studio (Web Studio will only open for other apps). Unfortunately from then on I can no longer see screen thumbnails and all connections are lost. Attempting to recreate connections to SharePoint online was unsuccessful (no error message appeared after clicking 'Select', yet no connection item appeared).

I have tried the following fixes to no avail;
-Renaming the app back to original name.
-Rolling back to previous versions.
-Checking trusted site settings in browsers - no problems there.

Any ideas? Thanks in advance!

Hi @Anonymous,

Please follow my posts in the following thread to configure the corresponding trusted site:

Infinite loop when playing PowerApp from tile

Also, verify the following configuration for PowerApps:

Limits and configuration in Microsoft PowerApps

If all are met, then please share your session ID (the one when you are trying to open the App in Edit mode), I will then help to forward that to the proper team for further investigation.

Regards,

Michael

Hi Thanks for your reply

All Trust settings are as per the suggestions at the first link. For the config details I will need ICT's help (I have logged a request). In the meantime I tried to get a session ID but can't see one in the address bar. Can you let me know how to go about getting the ID? Maybe the following from the browser View|Source menu is what you need ? ....

window._webAuthConfig={"webAuthoringVersion":"v2.0.640.0","aadClientId":"0cb2a3b9-c0b0-4f92-95e2-8955085f78c2","language":"en-US","cdnConfig":{"assetVersion":"39df24c99b63","cdnUrl":"https://paaseaucdn.azureedge.net"}};

Sorry for not being clear.

Session ID is under the

https://create.powerapps.com/ (PowerApps Studio for Web, Not the following: https://web.powerapps.com/)

Site, when navigate to Account tab in the Left Navigation pane, you will find Session Details, click it, then it will show you the Session ID.

Copy and paste that here.

Regards,

Michael

Michael, RickC's session ID indicates a problem handling his SPO connection. This is the "appoDataSourceConfig missing" error.

I have several PowerApps apps that all encountering the "UserInterventionNeeded_StorageLost" error when trying to use the Web Dev Studio... Windows Dev Studio seems to be working fine.

The problem occurs for others in my orgainization too. This issue arose all of a sudden - with no recent changes to the problematic apps.

I was able to get the PowerApp to work by adding https://us.create.powerapps.com to my list of trusted sites.

Something must have changed where this became necessary - I have been using PowerApps Web Studio fine until this week.

I just tried adding eu.create.powerapps.com to my trusted sites and I am still getting the same error with all our apps connected to CDN. We are using the eu location to host our apps.
