Posted on by Finnair 255

When opening app in Power Apps Studio, an error occurs:

 

WebAuthoring abnormal termination.

 

description: {"exception":{"message":"XMLHttpRequest error(string). {\"traceLevel\":3,\"message\":\"An unexpected error occured in InvokeService, activity id 8694f891-063e-415d-b7a4-a486bcc7de94\",\"status\":500}","name":"UnhandledError","_isCritical":true,"detail":{"exception":{}}},"error":"[circular]","promise":{"_oncancel":null,"_nextState":null,"_state":{"name":"error","enter":"[function]","cancel":"[function]","done":null,"then":null,"_completed":"[function]","_error":"[function]","_notify":"[function]","_progress":"[function]","_setCompleteValue":"[function]","_setErrorValue":"[function]"},"_value":"[circular]","_isException":false,"_errorId":35,"done":"[function]","then":"[function]"},"id":35,"setPromise":"[function]"}

 

The app doesn't open.

 

What to do?

    @Finnair 

    The first thing I'd try here is to clear the browser cookies, try using the 'in private' mode of the browser, or to try a different browser.

    Thank you @timl 

    These both tips have been already tried. MS Support suggested that the Authoring Version has changed. But trying to follow this advice but I cannot find Account-tab in Power Apps since I cannot open the app in Edit Mode:

    This started to happen to us too, tried multiple accounts but getting the same error in the studio.

    We are having the same issue.
    Thought it was a local problem at first, but it looks like it's a global problem. 

    WebAuthoring abnormal termination.

    We are having the same issue. Thought it was a local problem, but it looks like it a global problem.

    Same problem when trying to edit or create a new app from within Teams.

    Unfortunatly, this appears to be a global problem. I've heard from some users that MS have rolled back their authoring versions for them to fix this.

    @Finnair - hopefully, MS support were able to fix this for you?
