MarkBind version

3.1.1 - 5.5.2

Describe the bug and the steps to reproduce it

When markbind serve is run in stray directories (non-MarkBind configured folders), there is an uncaught exception that should be caught, or at least not shown to the user, to avoid confusion. (unless this is intentional).

The "path" argument must be of type string.

v3.1.1:

v5.5.2:

Minor nit to improve CLI experience.

Expected behavior

Error not shown.

Anything else?

Sounds like this error might be related to #2547 and #1825

Yes, I think https://github.com/MarkBind/markbind/issues/1825 is relevant to this issue. I guess it is a known behavior that markbind serve does not work in non-markbind directories, but improving the error handling/message is indeed good to have.
