Build trigger failed in Container Registry

[Dhandapani Sattanathan]

I created a trigger in Container Registry. I have my script in GIT HUB repo.

In Build trigger selected repository hosting option as GitHub and Authenticated.

STEP: 1: Selected git hub source repository

STEP:2: Selected my git hub repo and authenticated.

STEP 3: Created trigger using docker file option.

STEP 4: Trigger ran & I got build failed.

Build log

I got this issue unable to prepare context: unable to evaluate symlinks in Docker file path: lstat /workspace/Dockerfile: no such file or directory.

I don't know what I missed here. But each push in git hub trigger running automatically with build failed.

Please help me to fix this.
