Docker Space not triggering build despite valid Dockerfile and correct SDK

[SamPan-Git]

Describe the bug

Hi team,
I’ve created a Space via CLI using:
hf repo create tdsp1 --repo-type=space --space_sdk=docker
I’ve confirmed:

• The SDK is set to Docker in the Space settings
• A valid Dockerfile (capital D) is present in the root
• app.py and requirements.txt are present
• The app runs locally via Docker
• I’ve pushed multiple times and even triggered dummy rebuilds
  But: No build logs appear at all. The “Build logs” tab is empty, and the app doesn’t start.
  Space URL-

  Would appreciate help debugging this — happy to provide logs or try a fresh repro if needed.
  Thanks!
