DID document isn't saved after passwordless signup (anchoredDidElem is an excess property)

[dogada]

After passwordless signup using email browser (sdk 6.0.0-beta.20) sends to https://affinity-registry.prod.affinity-project.org/api/v1/did/anchor-did following data:

{
  "did": "did:elem:EiBDV8Srp_gnp2P-5CKnGePz9dcvTN3_WSiyj4-oGpMBRw;elem:initial-state=...",
  "didDocumentAddress": "",
  "ethereumPublicKeyHex": "",
  "transactionSignatureJson": "",
  "nonce": 0,
  "anchoredDidElem": false
}

and server response with error 400:

{"serviceName":"REG","code":"COM-3","message":"Invalid operation parameters.","context":{},"originalError":{},"httpStatusCode":400,"fields":{"anchorDidInput..anchoredDidElem":{"message":"\"anchoredDidElem\" is an excess property and therefore is not allowed","value":"anchoredDidElem"}}}
