When I try to update the schema configuration on a Hubspot Connector I get "An unknown error occurred. (HTTP 504)" repeatedly after the page almost freeze.

The HTTP 504 error you're seeing during schema discovery/refresh is a known timeout issue in Airbyte. It occurs when the schema discovery process takes longer than the server's configured timeout allows. [Schema Discovery Timeouts] How to Fix It You can increase Airbyte's timeout limits in your

values.yaml

Helm chart configuration: Helm chart V1:

server:
  extraEnv:
    - name: HTTP_IDLE_TIMEOUT
      value: 20m
    - name: READ_TIMEOUT
      value: 30m

Helm chart V2:

server:
  httpIdleTimeout: 20m
  extraEnv:
    - name: READ_TIMEOUT
      value: 30m

[Schema Discovery Timeouts] Additional Notes • If you are running Airbyte behind a load balancer (e.g., on DigitalOcean, AWS, etc.), you may also need to increase the timeout on the load balancer itself, as it may have its own hard timeout independent of Airbyte's configuration. [Review schema 504 timeout] • Some users have reported that even after increasing timeouts, the issue persists — in those cases, the root cause may be the connector itself taking an unusually long time to fetch the schema (e.g., a large number of objects/tables). [Facebook Marketing timeout] The knowledge sources don't contain a HubSpot-specific fix, but the timeout configuration above is the standard recommended approach for this class of error across connectors. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
