- [x] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

The indexer fails to process one of my files, a larger PDF (1678 KB). I've converted the file to an MD (318 KB) and it still fails with the same error. Small files work fine.

Any log messages given by the failure

When tasked to index the one file, after about five minutes, the script exits with this:

Error indexing files: Unexpected token 's', "stream timeout" is not valid JSON

Expected/desired behavior

Smaller files will result in the indexer script exiting with "indexed successfully".

OS and Version?

WSL version: 2.1.5.0
Ubuntu 20.04.6 LTS

azd version?

azd version 1.9.3

Versions
