The resolution of SWHIDs on n2t.net and identifiers.org does not work when using the new qualifiers introduced in SWHIDs v1.4
It is probably enough to update the regex used in these redirectors following what was done for Invenio for T1015 that can be found here
Currently the swh prefix description used by these two resolvers can be seen here (search for swh) : https://n2t.net/e/n2t_full_prefixes.yaml
