Unable to deploy pre-release of firestore-multimodal-genai

[cabljac]

We are unable to deploy the next version of firestore-multimodal-genai and it's blocking releases.

We suspect there is some platform issue with having this many roles.

to reproduce:

1. clone the repo
2. cd into firestore-multimodal-genai/functions on main
3. run npm i and npm run build
4. cd into _extensions
5. run firebase ext:install ../firestore-multimodal-genai --project=<PROJECT_ID>
6. run firebase deploy --project=<PROJECT_ID>

We get:

When a role is removed, it installs fine.
