Hi Railway team,

I'm experiencing an issue where custom service variables are not being injected into the runtime environment.

Details:

• Fresh minimal Flask app, fresh Railway project

• Service variables set directly in the service UI (TEST_VALUE, ZZZ_TEST, GROQ_API_KEY)

• Deploy succeeds, app is running

• Railway system variables arrive correctly (RAILWAY_ENVIRONMENT, RAILWAY_SERVICE_NAME etc.)

• But all custom variables return null at runtime via os.environ.get()

Proof via /health endpoint:

{"test_value": null, "zzz_test": null}

IDs:

• Project ID: 644d8ec3-15f7-4571-b474-3368d05db2ce

• Service ID: 138ee618-2645-4665-a82c-b8d5a293bba4

• Environment ID: 8dde830f-ca92-4196-a819-988f0147793d

• Domain: minimalapp-production.up.railway.app

Is there a known issue with custom variable injection in this environment?

Best regards GH

{"test_value":null,"zzz_test":null}
