Sentry React Native promise patching causes problems in ClojureScript advanced compilation

[viesti]

It seems that when using Sentry, promises break in ClojureScript advanced compilation. I didn't investigate too deep yet, but seems as if, for example in .then and p/then calls, the argument is somehow a promise and not the value.

Sentry documentation has instructions for disabling it's automatic patching of Promises, which seems to help: https://docs.sentry.io/platforms/react-native/troubleshooting/#disable-auto-patching

  (sentry/init
   (->js {...
          ;; Seems to break promises in CLJS advanced build
          :patchGlobalPromise false
...

Hmm, it is possible yes, because promesa has its own implementation of Promise for make it work in both mode: autflatten (.then) and not flatten (.fmap, same semantics as JVM completableFuture).

It is clearly a possible that something in sentry monky patching is doing that is not OK with our impl. We need research.

Thanks for reporting

Thanks for the fast response!

Wanted to leave this just as info if someone else runs into this, the :patchGlobalPromise false helped me :)

Promesa is cool! Don't want to force more new work for you :)

I can research what is going on if I have time :)

Any insight would be nice, because I'm not clearly know how to investigate this without running it in context of sentry.
