Description: Encountered a runtime panic during the startup of the OpenKF server component, specifically a nil pointer dereference error in the InfluxDB client initialization.

Steps to Reproduce:

  1. Deployed various services including Milvus, Minio, Redis, MySQL, etcd, and InfluxDB using Docker.
  2. Attempted to start the OpenKF server using Docker Compose.
  3. Observed that the OpenKF server failed to start, encountering a panic during the initialization phase.

Expected Behavior: The OpenKF server should start without errors and begin normal operation.

Actual Behavior: The server crashes immediately after starting, with a panic related to the InfluxDB client.

Environment:

  • OpenKF version: v0.2 (latest)
  • Operating System: Ubuntu (assumed based on command line)
  • Deployment method: Docker/Docker Compose

Logs/Screenshots:

[relevant log information from your provided logs]

Additional Information:

  • MySQL and Redis connections are established successfully, as indicated by logs.
  • The panic occurs specifically in the InitInfluxDB() function, with a nil pointer dereference in net/url.(*URL).ResolveReference.
  • This suggests an issue with the URL used for InfluxDB, possibly being nil or malformed.

Suspected Cause: There might be an issue with how the InfluxDB URL is being parsed or initialized in openkf-server/internal/conn/db/influxdb.go.

Possible Solutions:

  • Verify the InfluxDB URL configuration.
  • Check for any missing environment variables or misconfigurations related to InfluxDB.
  • Review the initialization code for the InfluxDB client in the OpenKF server application.
