What am I doing wrong here while using the API?

curl "http://url/rest/getMusicFolders" \
    --url-query u=$username \
    --url-query p=$password \
    --url-query v=$apiver \
    --url-query c=$clientstr

gives:

<?xml version="1.0" encoding="utf-8"?>
<subsonic-response openSubsonic="true" serverVersion="v3.70.0" status="ok" type="lms" version="1.16.0" xmlns="http://subsonic.org/restapi"><musicFolders><musicFolder id="1" name="Music"/></musicFolders></subsonic-response>

But when I do:

curl "http://url/rest/getMusicDirectory" \
    --url-query id=1 \
    --url-query u=$username \
    --url-query p=$password \
    --url-query v=$apiver \
    --url-query c=$clientstr

I get:

17:38
<?xml version="1.0" encoding="utf-8"?>
<subsonic-response openSubsonic="true" serverVersion="v3.70.0" status="failed" type="lms" version="1.16.0" xmlns="http://subsonic.org/restapi"><error code="10" message="Required parameter &apos;id&apos; is missing."/></subsonic-response>

What am I doing wrong here? Thanks.

Edit: This is my first time tryjng to use the API. The reason I expected this to work is because the subsonic api doc states this about the id parameter:

A string which uniquely identifies the music folder. Obtained by calls to getIndexes or getMusicDirectory.

So here I tried to use the id being returned by the folders API.

Hello!
Indeed you are supposed to use what you got using getIndexes or getMusicDirectory.
Here you tried an id that you got from getMusicFolders, which is another thing (music folders are actually called "libraries" in lms and a directory is just an actual directory located within a library)

I will try to make the error message more explicit, as it is actually here but not in the expected "format"
