docker cp - "Error response from daemon: not a directory"

Question

I am trying to copy file from docker to host using the below command,

docker cp <container_name>:<file FQN> ./

But getting the below error,

Error response from daemon: not a directory

As verified, the file name and container name are valid. Note: Using Docker in Mac

Thanks for all the answers. After a bit of struggle found out that the error message was not actually directly related to the docker cp command.

The scenario was, I ran the docker with the link to a local file. When the docker was running I deleted it. Then the file got created as a folder somehow (Probably, when I restarted the docker).

And whenever I am executing some command, the docker was giving me that error. Then once I created the file the error disappeared.
