There was a problem hiding this comment.
maybe "hydrate" -> "parse" ? or less verbose: "Excluding invalid CPE %q: %v"?

@kzantow I like that! I'll create a PR for this

Partially addresses #417.
When Grype reads in a user-supplied SBOM from Syft, it needs to convert CPE strings into CPE objects. When malformed CPE strings are supplied, Grype errored out and provided no useful results.
This PR adjusts the CPE parsing logic (within Syft JSON parsing) to log a warning instead of returning an error in the scenario where a user-supplied CPE string cannot be parsed successfully, allowing the logic to continue to other CPEs and other packages that don't have any parsing issues.
Note: We should also make an adjustment in Syft to avoid the creation of malformed CPE strings.
