my private git error failed to solve: failed to read Dockerfile

I am getting the following error when starting the deployment:
ERROR: failed to solve: failed to read Dockerfile: open /var/lib/docker/tmp/buildkit-mount2453544518/DockerFile: no such file or directory
However, the Dockerfile exists in my branch on my private GitLab repository. Why is this happening?

Can you share the structure of your project and how you are configuring the dockerfile path in your application?

develop branch on Repo in private gitlab:

my git config :
