Hi. I am having troubles getting the code to work. I downloaded the repo , docker desktop , python 3.10 and I am using PyCharm as an ide. i created a config file in the app folder and downloaded all the requirements. But when I try to run "docker build -t ${DOCKER_IMAGE_NAME}:${GIT_BRANCH}" . I am getting this error.
