ERROR: update returned updating certs: updating next batch of x509 certificates: fetcher: NonFatalErrors: asn1: syntax error: Value: PrintableString contains invalid character;
It could be that the golang x509 library used is too strict on checking the correctness of certificates and thus rejects certain certificates that the CT log accepted.
The map server uses the https://ct.googleapis.com/logs/xenon2023/ log and has no previously ingested certificates from this log.
