CHW-4002 CoordinateInvalid

package coordinate could not be parsed; supply name, version, and (where required) namespace in the format the ecosystem expects

Default message: package coordinate could not be parsed; supply name, version, and (where required) namespace in the format the ecosystem expects
HTTP status: 400 (client)

Problem. The package coordinate supplied in the URL or body could not be parsed. Cause. The ecosystem expects a specific shape (@scope/name@version for npm, group:artifact:version for Maven, name==version for PyPI, etc.) and the input did not match. Fix. Reformat the coordinate per the ecosystem’s convention and retry. HTTP 400.
