Hi, I've seen you changed some diagnostic structs in your PR. After #103345, the way we refer to fluent messages changed. They are now in a flat namespace with the same identifier as in the fluent file. For example, parser::cool_thing is now parser_cool_thing and parser::suggestion just suggestion.
You should rebase to the latest master and change your fluent message references as described above. Thanks!
