})

export { Sentry }

Additional Notes

• I referred to these docs
  • typescript
  • troubleshooting
• We have a mono-repo that contains various microservices, this one is called puppet-master
• Using sentry-cli version 2.45.0
• Our build process uses tsc to compile src into dist then tsc-alias to replace path aliases like @/ in dist
• I installed tslib as a dev dependency and added "noEmitHelpers": true and -"importHelpers": true. to tsconfig.json as per docs recommendations
• I've confirmed that
  • the compiled .js files have a sourceMappingUrl and debugId comment at the bottom of the file + a debug snippet (e.g. e._sentryDebugIds=e._sentryDebugIds||{},e._sentryDebugIds[n]="a13cd456-25a6-5f96-9f75-6deb567d5102")
  • the source map is being uploaded, and the release matches the Sentry SDK setup. Note that there is no debugId property which these docs specify there should be
• Here is an example .js.map file:

{
  "version": 3,
  "file": "auth.js",
  "sources": [
    "auth.ts"
  ],
  "sourceRoot": "/",
  "sourcesContent": [
    "import * as msal from ..."
  ],
  "names": [],
  "mappings": ";;AAAA,OAAO,KAAK,IAAI,MAAM,...",
  "debug_id": "fc4dfd90-2fe5-5a0e-bcc6-a22399856da8"
}

• The uploaded source map contains artifacts like ~/auth.js and ~/auth.js.map

Steps to Reproduce

import { Sentry } from './sentry.js'
import { throwError } from './tmp.js' // throw new Error('test error')

try {
  throwError()
} catch (err) {
  Sentry.captureException(err)
}

Expected Result

I would expect to see my code displaying within the event page

Actual Result

I do not see the code displaying within the event page

If I run sentry-cli sourcemaps explain $EVENT_ID --project $PROJECT"
then I see

⚠ DEPRECATION: `sourcemaps explain` has drifted from how sourcemap processing actually operates and its output may not be accurate. It will be removed in a future version of `sentry-cli`.
✔ Fetched data for event: 861ceb427ea74a9fb9d0e2ab8c69adeb
✔ Event has release name: 2.13.11
✔ Event has a valid exception present
✔ Event has a valid stacktrace present
✖ Event exception stacktrace selected frame (0) has incorrect abs_path (valid url is required). Found /tmp.ts

The event JSON is missing a debug_meta property and also includes:

 "errors": [
    {
      "type": "js_no_source",
      "symbolicator_type": "missing_source",
      "url": "/processVideo.ts"
    },
    {
      "type": "js_no_source",
      "symbolicator_type": "missing_source",
      "url": "/queue/queueReader.ts"
    },
    {
      "type": "js_no_source",
      "symbolicator_type": "missing_source",
      "url": "/tmp.ts"
    }
  ]

You can view the full JSON event here

If I can provide any more information (including access to the project) then please let me know.

Update: looks like the issue was caused by pm2
If I run the app with node then the debug_meta property is in the JSON and it works
