## AI-generated summary

A Shopify Remix app experiences a 500 server error when calling `authenticate.admin(request)` in production, though it works locally and returns 200 in Postman testing.

**Environment Details:**
- Recently migrated from SQLite to PostgreSQL
- Error occurs consistently in production regardless of request source
- Logs show: "No valid session found" → "Requesting offline access token" → 500 error

**Debugging Attempts:**
- Database connectivity verified - production DB accessible locally
- Prisma Session model and schema configuration confirmed correct
- Prisma Client debug mode enabled to capture database interactions
- Request headers, payloads, and responses logged throughout the flow
- CORS settings reviewed for cross-origin issues
- Authentication flow examined against Shopify requirements

**Key Observation:**
The error occurs *before* any attempt to create or retrieve a session from the Prisma database, suggesting the issue lies in the authentication middleware itself rather than database operations.
