What happened?

Biome 2.5.3 prints an internal panic while checking a small workspace repo that enables the project and types recommended domains. The same repo checks cleanly with Biome 2.5.2.

Minimal reproduction repo:

https://github.com/jakeleventhal/biome-253-module-resolver-panic-repro

Steps:

git clone https://github.com/jakeleventhal/biome-253-module-resolver-panic-repro.git
cd biome-253-module-resolver-panic-repro
bun install
bun check

Actual Biome 2.5.3 output:

$ biome check . --error-on-warnings
Biome encountered an unexpected error

Source Location: crates/biome_module_graph/src/js_module_info/module_resolver.rs:500:33
Thread Name: biome::workspace_worker_3
Message: index out of bounds: the len is 7 but the index is 11
Stack Trace: Re-run with `RUST_BACKTRACE=1` to capture the stack trace

packages/seller-utilities/trpc/src/trpc/routers/integrations/googleDrive/_router.ts internalError/panic  INTERNAL

  × processing panicked: index out of bounds: the len is 7 but the index is 11

Checked 13 files in 45ms. No fixes applied.

exit=0

The command prints an internal panic and checks only 13 of 14 files, but exits with status 0.

Control command with Biome 2.5.2:

bunx --bun @biomejs/biome@2.5.2 check . --error-on-warnings

Control output:

Checked 14 files in 35ms. No fixes applied.

exit=0

The reduced trigger appears to be the typed procedure/router graph in packages/seller-utilities/trpc/src/trpc/routers/integrations/googleDrive/_router.ts with this config:

{
  "linter": {
    "domains": {
      "project": "recommended",
      "types": "recommended"
    },
    "rules": {
      "correctness": {
        "noUndeclaredDependencies": "on"
      }
    }
  }
}

This may be related to #10884 because the source location is the same, but this report includes a public minimal repro and does not require noFloatingPromises or noMisusedPromises directly.

Expected result

Biome should not panic while checking the repo.

For this reproduction, Biome 2.5.3 should behave like 2.5.2: check all 14 files cleanly. If Biome encounters an internal error, the command should not silently exit with status 0 after skipping a file.

@ematipico appreciate the acknowledgement, but the acknowledgment is to Codex 😄

if i update biome to 2.5.3 bun check produces a bunch of errors. create a minimal reproduction repo and report a bug report template gh issue on the biome repository

i just ran that prompt and it produced this issue

I hit the same (at least I think so) panic in another repo and reduced it further to a small gist:

https://gist.github.com/kjanat/a2f6916e03ae00bc029075b2761b8836

• Biome 2.5.3
• Requires linter.domains.types = "recommended"
• srcRoot.length panics; srcRoot alone does not
• Removing the types domain avoids the panic
• RUST_BACKTRACE=1 only shows <unknown> frames in the npm binary

Panic:

crates/biome_module_graph/src/js_module_info/module_resolver.rs:500:33
index out of bounds: the len is 2 but the index is 3

This PR #10721 caused the regression. Fixing it now. cc @minseong0324 for visibility
