the `region` must be specified

Error message

the `region` must be specified

What it means

Configuration validation guard in the hcp-packer-artifact datasource's Configure. The datasource must know which cloud region the build artifact lives in so it can read the right registry entry; this sentinel error is appended to a MultiError when the required region field is empty. Set region in the datasource block to the region where the target artifact was built.
