Perforce depots not appearing in Code Mapping dropdown despite successful p4 depots query

Environment

SaaS (https://sentry.io/)

Steps to Reproduce

1. Install the Perforce integration with valid credentials.
2. Confirm the connection is working (server logs show successful user-login and user-depots commands from Sentry).
3. Confirm the configured service account has depot access by running p4 depots as that user.
4. Navigate to Settings > Integrations > Perforce > Configurations > Code Mappings > Add Mapping.
5. Observe that the depot dropdown is empty.

Additional Context

Removing and reinstalling the integration multiple times did not resolve the issue.
Server logs confirm user-login and user-depots commands are reaching the Perforce server successfully.
Running p4 depots manually as the service account returns the expected depots.

*user-reported bug. Intercom ticket #102195765

Expected Result

Depots accessible to the configured service account should appear in the dropdown.

Actual Result

The dropdown is empty, despite the server logs confirming that Sentry is successfully querying p4 depots and the service account having access to the depots.

Start by tracing the Perforce integration's user-depots result into the Settings > Integrations > Perforce > Configurations > Code Mappings > Add Mapping flow; the report names no files or tests. Reproduce with a valid service account and compare the returned depots with the dropdown options. Done means accessible depots appear in the dropdown.
