An annotation processor threw an uncaught exception.

You likely didn't merge the two branches together correctly. You may just want to wait for the dust to settle around the nb187 release and then I will update Punya accordingly.

Ammu · September 1, 2021, 5:29am

I already merge correctly but there is errors what I do now sir....

NishyanthKumar · September 1, 2021, 6:22am

He just wants you to wait until he can do something about it...

Ammu · September 1, 2021, 7:42am

But i need urgent please solve it...

NishyanthKumar · September 1, 2021, 8:15am

Unfortunately, that's something I can't do; the devs might have to take a look at this.

ewpatton · September 1, 2021, 1:46pm

Just because you resolved the merge conflicts syntactically doesn't mean you addressed the semantic issues raised by the merge. The error in question suggests to me that you either removed or swapped the order of some of the functionality added in Punya to handle generics in the type system (this functionality is not in App Inventor).

Ammu · September 1, 2021, 5:38pm

So sir, what I do now ???

Patryk_F · September 1, 2021, 6:49pm

Answer is here:

ewpatton · September 1, 2021, 8:02pm

I'm not sure why this is so urgent? This feature was only released last week...

As for how to fix your issue, you need to look at the two branches side by side and reason about how to merge the code while maintaining the semantics of both branches. This is usually a deeper task than just taking all one set of lines or the other, or both.
