Returning wrong file name

Assuming the following configuration:

new ParseServer({
    preserveFileName: true,
    filesAdapter: {
        module: '@parse/s3-files-adapter'.
        options: {
            directAccess: false,
            validateFilename(filename: string) { return null }
        }
})

And that it has a file saved with the following name: folder/bar-bar.jpg.

When I retrieve the file URL, the getFileLocation function returns: https://<MOUNT_PATH>/files/<APP_ID>/folder/bar-bar.jpg. However, this URL causes the parse-server to return an error: HTTP 403 - {"error":"unauthorized"}

The correct URL that should be returned is: https://<MOUNT_PATH>/files/<APP_ID>/folder%2Fbar-bar.jpg

I would like to know how you would like to solve this problem? Since the response may behave differently when directAccess is true or false.

Note: I encountered this problem while doing some tests with my PR https://github.com/parse-community/parse-server-s3-adapter/pull/117.

Start at the getFileLocation function and review the behavior described in pull request 117. Compare URL generation when directAccess is true versus false, including filenames containing folder separators; done means the returned URL is correctly encoded and no longer produces the reported 403 response.
