Issue Summary
Environment:
- App Framework: Shopify App with Remix template
- Database: PostgreSQL (Previously SQLite, recently migrated)
- Deployment: The app functions correctly in the local environment but encounters issues in production.
- Error Encountered: When calling authenticate.admin(request), a 500 server error is returned in production, while it works as expected locally.
- Postman Testing: The request to authenticate.admin(request) returns a 200 response in Postman.
Relevant Logs from Production:
- Shopify logs indicate
[shopify-app/INFO] Authenticating admin request
[shopify-app/INFO] No valid session found
[shopify-app/INFO] Requesting offline access token
size: 0, [Symbol(Body internals)]: { body: null, type: null, size: 0, boundary: null, disturbed: false, error: null }, [Symbol(Response internals)]: { url: undefined, status: 500, statusText: 'Internal Server Error', headers: {}, counter: 0, highWaterMark: undefined } }
- Steps Taken to Debug
Verified Database Connectivity:
- The production database is accessible as I can connect to it when running the app locally.
- Prisma client configuration was reviewed and confirmed to be accurate.
- Database connection was tested, confirming accessibility in production.
Session Storage and Prisma Configuration:
- The Prisma Session model is defined in the sessions schema with proper configuration.
- Schema:
prisma
model Session { id String
@Id shop String state String isOnline Boolean
@Default(false) scope String? expires DateTime?
@db.Timestamp() accessToken String userId BigInt? @@schema("sessions") }
- Prisma Client logs were enabled for query, info, warn, and error levels to track database interactions and identify if the session creation or retrieval process was problematic.
- Observed that the error occurred before any attempt to create or retrieve a session in the Prisma database.
Confirmed Postman Compatibility:
- A manual request to the endpoint via Postman returned a 200 response, confirming that the endpoint itself functions as expected when called independently.
Examined CORS and Authentication Flow:
- Verified that the app correctly handles authentication and makes requests according to Shopify’s requirements.
- Compared request headers and payload between Postman and the app to ensure consistency.
- Reviewed CORS settings to ensure there are no issues with cross-origin requests.
Captured and Reviewed Detailed Logs:
- Logged request headers, payloads, and responses in the app to capture all steps leading up to the error.
- Enabled Prisma Client’s debug mode to capture database-related issues, though no anomalies were found.
Error Consistency:
- The issue consistently occurs in production when making the authenticate.admin(request) call, regardless of the request source.
