Hey everyone,

 

Got this message when opening one of my model driven apps this morning. Anyone seen this before? Anyone have a solution?

    same problem today for me, but in a modern app, not canvas app

    did you solve it?

    It happened to me on a Model Driven app and I couldn't solve it. I just had to rebuild it quickly and then everything was fine.

    I've just had this happen on a customers App - how did you resolve?

    Many thanks.

    I have the same error again. Is there a solution without rebuilding the app?

     

    Many thanks

    I have raised a support ticket, just waiting for a reply. Will update once I've heard back.

    I have this issue too and would really hate to have to rebuild the app again due to the amount of effort the initial build took.

    Same problem here. Rebuilding the app is out of the question due to the size and would not work.

    There is a workaround...

     

    https://xxxxxxxxxxx.crm11.dynamics.com/main.aspx?flags=FCB.EnableAppActions=false&appid=xxxxxxxxxxxxxxxx 

     

    Just replace the 'xxxxxxxxxx's with the information for your organisation. You might need to contact MS support for them to implement a more permanent solution, but will report back tomorrow.

     

    Hope this helps.

    Thanks for this! It has worked for me after I had recreated my app. I now have a back up!

    I found a solution on this thread; Dynamics 365 Forum 

    Credit to Cassio in the thread for posting this findings. 

     

    Quick answer: It is a bug and to properly solve the problem, it must be done by the support side.

    Now, some insights and workarounds:

    • In my case, the problem is caused when I open the new app edit in preview mode. Even with no changes, it creates a dependent Component Library that cannot be deleted, and it breaks the app.
    • If it happened with a custom model-driven app, just create a new model-driven app using the same site map as the base. The new app will work fine.
    • A workaround to access the app is adding the flag &flags=FCB.EnableAppActions=false at the end of your app url
