Solutions

1. Make the connector report a valid SemVer version (e.g. 1.2.0)
2. Rebuild or re-fetch capabilities

semver::Version::parse(&capabilities.version)?;

Catch InvalidNdcVersion and report the raw version string and parse error.

When it happens

Trigger: Capabilities report a version like 'v1.2' or 'latest' that fails semver parsing.

Common situations: Custom/in-house connectors emitting non-SemVer version fields.
