I have following issue:

I have decited to post new issue because I probably have tried everything what I have seen on Internet...

The first problem:
I do not know why, but if i not upload manually source maps, then i will not see them on my project. Now i have everything automated so please help mi with the next one.

The second problem:
Like i wrote, I upload source maps by myself by this command after building release version via gitlab pipeline:
./node_modules/@sentry/cli/bin/sentry-cli releases files $PACKAGE_NAME@$CURRENT_VERSION_NAME+$CURRENT_VERSION_CODE upload-sourcemaps --dist $CURRENT_VERSION_CODE --strip-prefix . --rewrite android/app/build/generated/assets/react/release/android.main.bundle android/app/build/generated/assets/react/release/android.main.bundle.map
and the result in console is

Analyzing 2 sources
Rewriting sources
Adding source map references
Bundled 2 files for upload
Uploaded release files to Sentry
File upload complete
Source Map Upload Report
Minified Scripts
~/android.main.bundle (sourcemap at android.main.bundle.map)
Source Maps
~/android.main.bundle.map

and in the Sentry project:

but when i open any issue connected with the same release name and dist I get:

Can anyone help me with this?

Same problem here

[jennmueng]

Hey guys, so the name of the bundle/sourcemap has to match exactly. In the stack trace it's index.android.bundle while in the artifacts you have it uploaded as android.main.bundle. If you can rename the bundle and source map to index.android.bundle and index.android.bundle.map and reupload them they should work.

[rafalkowalewski]

@jennmueng thank you for your reply!
You are right and now I am one step further, but still not there where I want to be 😄

I changed name and now I see more than before, but this is still unreadable 😞
Do you have any idea what else should I change?

Hmm this looks like a bad source map. Can you try manually bundling the source map with

react-native bundle \
  --dev false \
  --platform {PLATFORM} \
  --entry-file index.js \
  --bundle-output ./build/index.android.bundle \
  --sourcemap-output ./build/index.android.bundle.map

and uploading that to sentry?

[rafalkowalewski]

I do exactly this:
react-native bundle --dev false --platform android --entry-file index.js --bundle-output index.android.bundle --sourcemap-output index.android.bundle.map
and then:
./node_modules/@sentry/cli/bin/sentry-cli releases files $PACKAGE_NAME@$CURRENT_VERSION_NAME+$CURRENT_VERSION_CODE upload-sourcemaps --dist $CURRENT_VERSION_CODE --strip-prefix . --rewrite ./index.android.bundle ./index.android.bundle.map

[lucianomlima]

Same here, only with Android source maps in RN 0.61.5 with Hermes enabled and using Code-Push and @sentry/react-native v1.5.0

[rafalkowalewski]

@jennmueng do you have any other idea to fix this issue?

I still have the problem on production and it is very difficult to analyze an errors there

[jennmueng]

@rafalkowalewski From the screenshots it looks like Sentry still isn't correctly detecting the source maps.. does the error "Source code was not found" still showing at the top?

[rafalkowalewski]

There was nothing but I found in the new one something like this - maybe it is connected to that.

[jennmueng]

Sorry for the late reply, we've been looking into the timestamp issue for a past couple of days, and I've made an issue specifically for it. However it shouldn't have any effect on sourcemaps.

[mym0404]

I am experiencing same thing.
React Native : 0.63.2
Sentry SDK : 1.6.3

Previously, when I upgraded sentry sdk, the source map was uploaded and I could see a well parsed stack trace.
But suddenly, stack trace has been broken.

[jennmueng]

@mym0404 Do you have any errors displaying at the top of the issue page where the source map doesn't work?

[mym0404]

No just timestamp error is showing

[jennmueng]

@mym0404 Can I have the full (not the share) link to the error? I will investigate this.

[mym0404]

@jennmueng It is weird. In the same release, some errors in the same platform(android), somethings are parsed with the correct source maps but others not.

One question, at that error invocation time, whether the source maps are already uploaded affects source map parsing?

Thank you for your attention.

[jennmueng]

@mym0404 Yes the source maps need to be present before the error occurs for them to be parsed. We currently don't support processing events after they've been saved to our backend, they're only processed once when they're received.

[jennmueng]

@rafalkowalewski I just found out about a prior issue for source maps on Android, it was before I joined Sentry so I had no knowledge of this my apologies. Can you try this fix and see if it solves your issue?

[rafalkowalewski]

@jennmueng thank you for your message. I will let you know this/next week if it is work. I am going to release a new production version :)

[15matias15]

Hey @rafalkowalewski were you able to solve the issue? I'm facing the same problem on my project

[patelnets]

this worked for me, producing the full stack trace on android

Create the source maps
react-native bundle --dev false --platform android --entry-file index.js --bundle-output index.android.bundle --sourcemap-output index.android.bundle.map

Upload the created source maps to sentry
./node_modules/@sentry/cli/bin/sentry-cli releases --org <ORG> --project <PROJECT> files <APPLICATIONID>@<VERSION>+<BUILD> upload-sourcemaps --dist<BUILD> --strip-prefix . --rewrite ./index.android.bundle ./index.android.bundle.map

Where VERSION is of format 1.4.6
BUILD is like 123
APPLICATIONID is like uk.co.examplecompany.android

[15matias15]

@patelnets do you have Hermes enabled?

[patelnets]

Ah nope. Sorry i didn't read all the comments

[rafalkowalewski]

Hey @rafalkowalewski were you able to solve the issue? I'm facing the same problem on my project

No :( i am still facing with it. I will let you know if i find some solution.

[15matias15]

@rafalkowalewski thanks, I'll let you know too if I found something

[jennmueng]

Hey @rafalkowalewski were you able to solve the issue? I'm facing the same problem on my project

No :( i am still facing with it. I will let you know if i find some solution.

@rafalkowalewski Did the solution on prior issue I sent not work?

[rafalkowalewski]

I wanted to tell you it works! :) but I had to modify it a bit and now everything looks pretty good.
Here is my script:

mkdir bundle
npm run react-native -- bundle --dev false --platform android --entry-file index.js --assets-dest bundle --bundle-output bundle/index.android.bundle --sourcemap-output bundle/index.android.bundle.map
node_modules/hermes-engine/win64-bin/hermesc -emit-binary -out bundle/index.android.bundle.hbc bundle/index.android.bundle -output-source-map -w
node node_modules/react-native/scripts/compose-source-maps.js bundle/index.android.bundle.map bundle/index.android.bundle.hbc.map -o bundle/index.android.bundle.map
npm run sentry -- releases files $PACKAGE_NAME@$CURRENT_VERSION_NAME+$CURRENT_VERSION_CODE upload-sourcemaps --dist $CURRENT_VERSION_CODE --strip-prefix . --rewrite ./bundle

IMPORTANT INFO:
select the proper hermes file depending on your system

[15matias15]

@rafalkowalewski what do you do on npm run sentry ?
Are you getting those files too?

[rafalkowalewski]

Oh sorry... i forgot to explain it.
It runs sentry cli. I do not have it globally, so i do it via „npm run” to run it from node_modules.

[15matias15]

@rafalkowalewski thanks. Do you have the same 3 files on your sentry artifacts?

[rafalkowalewski]

@rafalkowalewski thanks. Do you have the same 3 files on your sentry artifacts?

Yes, exactly 😃

[jennmueng]

That's great, looks like we can close this?

[15matias15]

@jennmueng I still have one issue, but not related to sentry. We use mobx & mobx-react to handle the store with @inject decorator and we have the next component:

@inject (STORE)
<HOC>
--a 2º HOC with another inject--
@inject (STORE)
<2HOC>
<COMPONENT>
</COMPONENT>
</2HOC>
</HOC>

I put a throw new Error() on the component and sentry it's showing me this
Error observable(XXX/XXX/react/main/stores/STORE)
and this as stack trace

any idea??

[rafalkowalewski]

That's great, looks like we can close this?

Yes :)

[freemile2ru]

I still have this issue I have tried everything I can find on the internet but no luck
