Ah in this thread The "Body does not pass verification" error from a Motoko canister - #4 by nomeata @nomeata provided an example

github.com

nomeata/motoko-certified-http/blob/master/main.mo#L164


      
          too strict and will not allow the following, and there is no `system func init` in Motoko:
          */
            // update_asset_hash();
          
          
/*
          The other use of the tree is when calculating the ic-certificate header. This header
          contains the certificate obtained from the system, which we just pass through,
          and our hash tree. There is CBOR and Base64 encoding involved here.
          */
          
          
  func certification_header() : HeaderField {
              let cert = switch (CertifiedData.getCertificate()) {
                case (?c) c;
                case null {
                  // unfortunately, we cannot do
                  //   throw Error.reject("getCertificate failed. Call this as a query call!")
                  // here, because this function isn’t async, but we can’t make it async
                  // because it is called from a query (and it would do the wrong thing) :-(
                  //
                  // So just return erronous data instead
                  "getCertificate failed. Call this as a query call!" : Blob
