Sentry's sourcemaps/artifacts don't work

I'm building, minifying and generating sourcemaps of my app with webpack. Artifacts are sent to sentry.io with webpack-sentry-plugin.

The javascript code is run from localhost:8080/js/app.js. It contains //# sourceMappingURL=app.js.map at the end. Sourcemaps work correctly at Chrome devtools.

Sentry's Releases/Artifacts contain the following files:

js/app.js
js/app.js.map

Anyway, when Sentry logs an error, stacktrace is from the minified file. It's not using the sourcemaps.

What am I doing wrong in my setup? Or what other info should I give to get help?

In our case, it hasn't been working for a loooong time.

Everything seems to be just fine. Artifacts uploaded, versions tagged, errors logged, but no sourcemaps.

Bottom line of the issue: We are hosting Sentry ourselves and sentry is divided into different containers. They did not properly share the data.

One solution is to share the data between containers (see that post) or to even upload your sourcemaps to an S3 server and Sentry can also work with that.

I posted this question at forum.sentry.io and got the answer from a guy called @benvinegar.

Here is the thing: when sending a sourcemap/artifact, we provide the file and also a filename. The filename is meant to be the complete URL where the sourcemap would be located if it was uploaded to the host together with the minified JS files. That is: if our minified Javascript is located at www.example.com/js/app.js, then the sourcemap/artifact filename must be www.example.com/js/app.js.map. Otherwise, we can name it ~/js/app.js.map if we want the sourcemap to apply to other situations like running the app at localhost:8080/js/app.js.

As I'm using webpack-sentry-plugin, it was just a matter of adding the following property to the plugin:

{
  plugins: [
    new SentryPlugin({
      filenameTransform: filename => '~/' + filename
    })
  ]
}
