Document XMP metadata

Photoshop
6

Your solution work for me until set the metadata with the batchplay code. It didn’t edit the metadata and didn’t return any error. Do you have any ideas to why? I change the code a bit

const bp = require("photoshop").action.batchPlay;
const getDocumentXMP = () => {
  return bp([{
    _obj: "get",
    _target: {
      _ref: [
        { _property: "XMPMetadataAsUTF8" },
        { _ref: "document", _enum: "ordinal", _value: "targetEnum" }
      ]
    }
  }], { synchronousExecution: true })[0].XMPMetadataAsUTF8
}
const setDocumentXMP = (xmpString) => {
  bp([{
    _obj: "set",
    _target: [
      { _ref: "property", _property: "XMPMetadataAsUTF8" },
      { _ref: "document", _enum: "ordinal", _value: "targetEnum" }
    ],
    to: {
      _obj: "document",
      XMPMetadataAsUTF8: xmpString
    }
  }], {});
}
const getDocumentMetadata = (key, prefix) => {
  const xmpString = getDocumentXMP();
  const obj = convert(xmpString, { format: "object" });
  return obj["x:xmpmeta"]['rdf:RDF']['rdf:Description'][`${prefix}:${key}`] || "";
}
const setDocumentMetadata = (key, value, prefix) => {
  const xmpString = getDocumentXMP();
  const obj = convert(xmpString, { format: "object" });
  obj["x:xmpmeta"]['rdf:RDF']['rdf:Description'][`${prefix}:${key}`] = value;
  const newXmpString = convert(obj, { format: "xml" })
  setDocumentXMP(newXmpString);
}
try {
  setDocumentMetadata("CreateDate", "1", "xmp");
} catch (error) {
  console.log(error.message);
}
