Docker Space Runs Normally but Run Logs Only Show “Application Startup” Banner, No Container stdout/stderr

Thanks for the troubleshooting guidance.

We followed your suggestion and deployed a probe build on our Docker Space:

• Space: Bin29/ManimCat
• Probe commit: 100c4b9
• Probe behavior: forced BOOT_STDOUT, BOOT_STDERR, and periodic HEARTBEAT_STDERR to stderr every 15s at container startup.

Observed results:

1. Runtime is healthy:
   • stage = RUNNING
   • replicas = 1/1
   • domain = READY
2. App is serving traffic:
   • GET /health returns 200 with redis=true, queue=true, openai=true
3. Build logs are complete and normal.
4. Run logs still show only:
   • “===== Application Startup at … =====” and no probe lines (no BOOT/HEARTBEAT output at all).

So this looks like run-log forwarding/viewer path issue rather than app logging config. We have reverted the probe commit to restore normal behavior:

• Revert commit: 0a6c24b

Could you please check backend log forwarding for this Space (Bin29/ManimCat), especially around the timestamps when probe commit 100c4b9 was running?
