"Permission denied (os error 13)" by running Function on Docker local-dev

[Pictor13]

On local-development there seems to be an issue with filesystem permissions over the deno Docker container.

When trying to access an Edge Function file, Deno fails with error: Permission denied (os error 13).
I docker-exec -it $deno_container bash into docker ps | grep deno and can see that:

• id returns the user deno, having UID & GID equal to 1993
• ls -la /home/deno/functions/my-function/index.ts shows onwer UID and group GID as equal to 1000
  • uid/gid 1000 is usually corresponding to the docker user; when it appears in a container usually is the sign of some volume mount of some sort.

Is this the case?
I saw the /app/Dockerfile simply copies the files, from localhost to the container, but I don't see why they should have this mismatching file permissions.

Can somebody check in their working docker local-dev if the 2 commands above return the same results as me?

At the moment I am unable to test functions locally.
What could be causing the error?
What can I try to restore the correct functionality?
Could this be a bug?

I run:

• supabase start
• supabase functions serve my-function --debug

it outputs:

Additionally

• I also tried supabase stop and start again to see if it would reset the image & containers, but nothing changed
• I tried to chmod 777 the index.ts file inside the container but user deno has no rights to do so and sudo is not available.
