Hosting Langflow on Railway and none of the database connectors do anything

[christo9090]

I deployed to railway using the railway template in the docs. But after you do, none of the database connectors work. Everything else works. But when I put in keys for Astra, none of the DB or collections show up. I tried pinecone and the flow appears to run fine with no issues but nothing is actually saved to pinecone. I feel like I am missing something in the build process. Ideas?

Hey there, @christo9090! I'm here to help you with any bugs, questions, or contributions while you wait for a human maintainer. Let's tackle this issue together!

I found a similar closed issue related to database connectivity in Langflow: Docker 1.0.16 image does not work with Postgres. This issue was resolved by a pull request that fixed a missing module named 'psycopg2' ^[1].

For your specific issue with Astra and Pinecone, ensure that you have set the required environment variables correctly:

• For Pinecone:

  • PINECONE_API_KEY

• For Astra:

  • ASTRA_DB_APPLICATION_TOKEN
  • ASTRA_DB_API_ENDPOINT ^[2].

Additionally, verify that the initialization and connection code for these databases is correctly configured. For Astra, the AstraVectorStoreComponent class in AstraDB.py handles the connection setup. For Pinecone, the initialize_pinecone function in vector_store.py is responsible for setting up the connection ^[3][4].

Make sure these configurations are correctly implemented in your deployment on Railway. If the issue persists, consider checking the logging and debugging information provided by Langflow to identify any specific errors or issues with the database connectors ^[5].
