AsnConvert.serialize & primitive values

[ghost]

For example if I want to serialize a BasicOCSPResponse which in turn has a ResponseData that has the attribute producedAt: Date

This snippet fails with Error: Cannot get schema for 'Object' target

AsnConvert.serialize(
  new OCSPResponse({
    responseStatus: OCSPResponseStatus.successful,
    responseBytes: new ResponseBytes({
      response: new OctetString(
        AsnConvert.serialize(
          new BasicOCSPResponse({
            tbsResponseData: {
              producedAt: new Date(),
              responses: [],
              responderID: new ResponderID(),
              version: Version.v1,
              responseExtensions: [
                {
                  critical: false,
                  extnID: id_pkix_ocsp_nonce,
                  extnValue: new OctetString(Convert.FromHex("FFF")),
                },
              ],
            },
          })
        )
      ),
    }),
  })
);

Is there a workaround for this?
