Hi! Thanks for mentioning me.

Yeah, this update will fix it. The error happened because Scorecard uses Sigstore tool to sign its results and Sigstore has done an update (https://blog.sigstore.dev/tuf-root-update/) that is not compatible with older Scorecard versions (for example, v.2.1.2 used here). But Scorecard v2.3.1 is compatible with Sigstore changes and should get back to work smoothly =)
