I was playing around with Render when trying to get multiline environment variables to work.
My plan was to add a secret env file and then changing the Docker Command to load it into the environment. So I changed the Docker Command to something like this:
export FOO=$(cat .my-multiline-env-var) && node index. I then noticed that the Docker build fails without displaying any error log which makes debugging kind of impossible.
Then I played around with the Docker Command itself and noticed that the build also fails when I paste the exact CMD I am using in the Dockerfile successfully.
Every time I tried to copy the command that I used in Docker Command (which would result in a failed build) into the shell the command worked without error.
