I have following issue:

My bundle is not producing any sourcemaps and then the upload of the sourcemap fails.
I think there is an issue with forcing sourcemap output:
My default bundle command does NOT have a --sourcemap-output in.
It starts here https://github.com/getsentry/sentry-react-native/blob/master/sentry.gradle#L45
Then here https://github.com/getsentry/sentry-react-native/blob/master/sentry.gradle#L212 it tries to get the sourcemapOutput path.
So these lines wont find a sourcemapOutput https://github.com/getsentry/sentry-react-native/blob/master/sentry.gradle#L180-L186 BUT then here
https://github.com/getsentry/sentry-react-native/blob/master/sentry.gradle#L195-L198 some weird sourcemapOutput is returned.
So the script thinks there was a --sourcemap-output defined and does not force the arg, hence no sourcemap will be generated but it still expects a sourcemap to be there.

Or am I missing something?

Steps to reproduce:

• use rn 0.59.10 and sentry 1.3.0

Actual result:

• no sourcemap generated

Expected result:

• a sourcemap generated

Sorry about that, we'll take a look.

@muxe hey, I've raised a PR #777 could you just copy/paste that part of the code and try this out? thanks :)

[muxe]

Thanks. I'll give it a go, but not before monday though.

I am not quite sure, but I think my --bundle-output is set but not the --sourcemap-output.
This should then still return a sourcemapOutput !== null from extractBundleTaskArguments which again leads to no args added here https://github.com/getsentry/sentry-react-native/blob/fix/sourcemaps_folder/sentry.gradle#L220-L224

But as I said this only by looking at code, I would need to run this to see how it behaves.

@muxe sure :) but I'd say that in your case --sourcemap-output is not passed at all, this thing was implemented later than your react-native version 0.59.10, let me know your findings, thanks.

Fixed by #777

@amogh-jrules mind filling a bug with all the versioning + logs? thanks :)
