failed to initialize bucket %q: %w

Error message

failed to initialize bucket %q: %w

What it means

HCP registry error from Bucket.Initialize: the initial upsert of the bucket against the HCP Packer API failed (creation/lookup of the image and its version). The wrapped error carries the HTTP/API cause — auth failure, invalid credentials, or connectivity problems.

Solutions

1. Verify HCP_PACKER_CLIENT_ID/HCP_PACKER_CLIENT_SECRET (or HCP_API_TOKEN) are set and valid
2. Check network access and HCP status page; retry the build for transient outages
3. Confirm the bucket name is a valid slug accepted by HCP
