Bad type for files in submission of a reference solution #535

I am trying to submit a reference solution to ReCodEx via CLI and it fails because of the type annotation of files argument in the swagger:

When I manually changed it to follow the type for files in pre-submit:

then the submit from CLI worked.

Claude convinced me that the swagger is generated wrongly because of the type of files in the line below

which should be VArray as in pre-submit:

but I am leaving that for you to judge.
