invalid argument running docker-compose up

Question

I am new to docker, trying to run docker image locally according to instruction here

I pull the image by docker pull puckel/docker-airflow, then prepare the .yml file and run docker-compose up -d but keep showing the error:

Error response from daemon: readlink /var/lib/docker/overlay2/: invalid argument

Not sure which part is missing here.

Answer 1

Check your .env file. There will be some invalid syntax.
