feat(sourcemaps): Inject `debugId` into sourcemaps, not `debug_id` by szokeasaurusrex · Pull Request #3005 · getsentry/sentry-cli

szokeasaurusrex · 2025-12-03T16:54:25Z

Align debug ID injection with the relevant TC39 proposal by upgrading the sourcemap crate to 9.3.0, which serializes the Debug ID on a sourcemap under the "debugId" key, instead of the "debug_id" key. The crate still supports reading the "debug_id" key, but the "debugId" key takes precedence if both keys are present.

These changes primarily affect the sourcemaps inject command, which will now place the debug ID in the "debugId" field rather than the "debug_id" field. The sourcemaps upload command is also affected, as sourcemaps will be rewritten with "debugId" rather than "debug_id". Previously, rewriting preserved the key being used; if a sourcemap contained both keys, both would have been preserved after rewriting, but after these changes, we emit only "debugId". For example, if a sourcemap contains only the "debug_id" key, the rewritten sourcemap will have that key in "debugId" instead; however, if a sourcemap contains both the "debugId" and the "debug_id" keys, the "debug_id" is completely stripped, and its value ignored.

CLI-44 [Time Capsule - DON'T OPEN BEFORE NOV 6 2025] Emit `debugId` instead of `debug_id`

…134) The debug ID field on all source maps is now **serialized as `debugId` rather than `debug_id`**. To maintain backwards-compatibility with source maps that contain a `debug_id` field, we can still read the `debug_id` field. If a source map contains a `debugId` field and a `debug_id` field, **the `debugId` field takes precedence, which is a change from the old behavior**. Corresponding Sentry CLI PR: getsentry/sentry-cli#3005 Closes #96 Closes [CLI-240](https://linear.app/getsentry/issue/CLI-240/turn-debug-id-field-to-debugid)

Bundle ID changes because the rewritten sourcemap contains debugId, not debug_id. Elsewhere, the hashes we are checking are changing for the same reason

As debugId is now the default, I inverted this test as part of this change.

Sorry, just to understand this: the test fixture already contained both debug_id and debugId with different values, so you just need to change from one value to the other here?

Ok, I guess what I wrote was a bit misleading, I also kinda forgot exactly what I did here 😅

The test previously was checking that if we had "debug_id" and "debugId", we select the "debug_id". I changed the test instead to check that if we only have "debug_id", we can still read the "debug_id". I don't have a test right now that checks the precedence (although, I think it is also fine to keep things that way, as I think this is more an internal detail of the sourcemap create).

"debug_id" still has the same value it had before. This is the relevant fixture, you can see that I just removed the "debugId".
