If there is error in async function UXP won’t tell you it. So you have wrap into try/catch every single async function in your plugin and rethrow that explicitly otherwise you will have no idea about an error. Also I want to integrate Sentry. I can add Sentry for Browser. I can also explicitly send…

+1 For this issue. We really need better errors in UXP for debugging and error reporting with systems like Sentry.

I asked Sentry for workaround. They don’t see any good one. How to workaround non-existent `onunhandledrejection` in Adobe UXP (Javascript) · getsentry/sentry-javascript · Discussion #12338 · GitHub

I also agree. I have Sentry integrated into one of my plugins, but I am wrapping the code in try/catch as you mentioned. I only added it to parts which I think are critical but it’s cumbersome and I may miss errors.

This works in Chrome but I can’t make it work in UXP GitHub - rtsao/browser-unhandled-rejection: A ponyfill/polyfill for browser Promise unhandledrejection events Can anyone figure out why?

Yes please. Log uncaught errors in promises.

Any updates on this? This is one of the big reasons why devs run away from UXP to something less painful. @indranil @Sujai

Agreed. Gets cumbersome and error prone to manage potential for rejected promises with things like button handlers.
