Complete log with PACKER_LOG=DEBUG: scw_packer_snapshot.log

Moreover in the documentation : Config-not-required.mdx and Scaleway Packer integration doc, default value for image name and snapshot name in the documentation are missing the prefix image- and snapshot- respectively:

snapshot_name (string) - The name of the resulting snapshot that will appear in your account. Default packer-TIMESTAMP

whereas the default value is defined as snapshot-packer-{{timestamp}} code

image_name (string) - The name of the resulting image that will appear in your account. Default packer-TIMESTAMP

whereas the default value is defined as image-packer-{{timestamp}} code
