The workaround is to add """" as the comment input.

I get a different error than you, but just to confirm I also cannot release a lock without providing input to the Comments parameter. Here's the error I get: Internal : The parameterized query '(@eventCode nvarchar(4),@narrative nvarchar(84),@sourceUser uniq' expects the parameter '@comments', which was not supplied.
