error hashing manifest location: %v

Error message

error hashing manifest location: %v

What it means

Same hashing step as error 36 but for the manifest location URL: ParseAddons hashes the location string to build the addon name 'manifest-<hash[:12]>'. The wrapped error from utils.HashString indicates an essentially impossible internal failure.

Solutions

1. Retry the operation.
2. Rebuild/redeploy the binary.
3. File an upstream issue if reproducible, including the manifest location string.

addons, err := channels.ParseAddons(name, location, data)
if err != nil {
	if strings.Contains(err.Error(), "error hashing manifest location") {
		retryWithBackoff(2, func() error { _, err = channels.ParseAddons(name, location, data); return err })
	}
	return err
}

When it happens

Trigger: LoadAddons -> ParseAddons else-branch with a non-Addons manifest where utils.HashString(manifest) fails. No realistic input causes this; it is defensive error handling.

Common situations: Not seen in real deployments; only plausible with memory corruption or OOM conditions.
