I have following issue:

When trying to bundle a custom buildType on android I get:

> Task :app:bundleAlphaJsAndAssets_SentryUpload_20 FAILED
Processing react-native sourcemaps for Sentry upload.
error: No such file or directory (os error 2)

Add --log-level=[info|debug] or export SENTRY_LOG_LEVEL=[info|debug] to see more output.
Please attach the full debug log to all bug reports.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:bundleAlphaJsAndAssets_SentryUpload_20'.
> Process 'command 'node_modules/@sentry/cli/bin/sentry-cli'' finished with non-zero exit value 1

I have tried adding the following:

project.ext.sentryCli = [
    logLevel: "debug",
    flavorAware: true
]

in app/build.gradle but now I get:

> Task :app:bundleAlphaJsAndAssets_SentryUpload_20 FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:bundleAlphaJsAndAssets_SentryUpload_20'.
> java.lang.NullPointerException (no error message)

Steps to reproduce:

• Add a custom buildType in the buildTypes section of:

alpha {
        initWith release
        matchingFallbacks = ["release", "debug"]
        applicationIdSuffix ".alpha"
}

• Bundle the app

> cd android
> ./gradlew clean && ./gradlew assembleAlpha

Important note:
Doing the same for Release is working (./gradlew assembleRelease).

I found out that disabling Hermes would solve the issue.

Hi @MathieuUrstein,

I don't think this is a Sentry issue, I had a similar issue because of this line. Basically in the react-native gradle task, if your variant doesn't include release in the name, it won't output the sourcemaps.

3 solutions:

• rename your build type to include "release" in the name
• add a patch to react-native to replace this line and include alpha
• I've also submitted a PR to RN, hopefully will get some feedback

Thanks for clarifying this up. It's correct. I close the issue.
