version %s of %s is not listed in %s/%s/index.json

Error message

version %s of %s is not listed in %s/%s/index.json

What it means

Remote-mirror getter error from versionURL: the requested plugin version is not present in the mirror's index.json for that plugin type, so its download URL cannot be resolved. The mirror is out of sync or the version was never published there.
