Dockerfile: Failed to compute cache key: "/tsconfig.json": not found

Question

I'm currently trying to set up GitHub actions, to automatically build and push a backend to DockerHub. However, if the workflow build-and-deploy-backend is triggered it starts creating the Docker Image but fails at the line 23 in the server/Dockerfile:

  22 |     COPY ./src ./src
  23 | >>> COPY ./tsconfig.json ./

See: https://github.com/bennodev19/dronies-watch/runs/4813916640?check_suite_focus=true

with this Error:

Dockerfile:23
--------------------
  21 |     # Move required app source into the working directory referenced with './'
  22 |     COPY ./src ./src
  23 | >>> COPY ./tsconfig.json ./
  24 |     
  25 |     # For debugging:
--------------------
error: failed to solve: failed to compute cache key: "/tsconfig.json": not found
Error: buildx failed with: error: failed to solve: failed to compute cache key: "/tsconfig.json": not found

See: https://github.com/bennodev19/dronies-watch/runs/4813916640?check_suite_focus=true

Locally it builds without any problem. Tested on MacOS and Windows 10.
