path_for_auxiliary_executable is not available on the web

Error message

path_for_auxiliary_executable is not available on the web

What it means

Sentinel from the web platform's path_for_auxiliary_executable: browsers cannot resolve bundled helper executables, so the lookup always fails with this error on the web regardless of the name passed.

Solutions

1. Feature-gate auxiliary-executable usage out of web builds
2. Ship helper functionality as web APIs/WASM instead of separate binaries
3. Handle the Err at call sites to disable dependent features on the web
