I launched both reev services using:

https://github.com/bihealth/reev-docker-compose

The frontend sends requests like:

http://localhost/internal/proxy/viguno/hpo/genes?gene_id=HGNC:1100&hpo_terms=true

But Viguno expects:

http://localhost/internal/proxy/viguno/api/v1/hpo/genes?gene_id=HGNC:1100&hpo_terms=true

When I manually test with curl, the version with /api/v1/ returns data correctly.

The version without /api/v1/ gives a 404 Not Found.

It seems the frontend is missing the /api/v1 segment in its base_url for Viguno.

Expected Fix
Update the frontend configuration so that Viguno requests use:

/internal/proxy/viguno/api/v1
as the base path.

Please let me know if this path change should be made in a specific config file, or if there's an environment variable intended for this.

Thanks!
