How to use the dummy-json.parse function in dummy-json

ids.map((j) => {
        // We use a template so that each time the message can be randomly generated.
        const generatedMessage = isTemplate
        ? dummyjson.parse(template)
        : template;
        this.sendD2CMessageCore(
          clients[j],
          generatedMessage,
          statuses[j],
          this.totalStatus,
        );
      });
      this.totalStatus.addSent(deviceCount);

export const DummyJSONParser = (text: string, request: any): string => {
  return DummyJSON.parse(text, { helpers: DummyJSONHelpers(request) });
};

node.on("input", function(msg) {
            if (msg.seed) { dummyjson.seed = msg.seed; }
            try {
                var value = dummyjson.parse(node.template, {mockdata: msg});
                if (node.syntax === "json") {
                    try { value = JSON.parse(value); }
                    catch(e) { node.error(RED._("datagen.errors.json-error")); }
                }
                if (node.fieldType === 'msg') {
                    RED.util.setMessageProperty(msg,node.field,value);
                }
                else if (node.fieldType === 'flow') {
                    node.context().flow.set(node.field,value);
                }
                else if (node.fieldType === 'global') {
                    node.context().global.set(node.field,value);
                }
                node.send(msg);
            }
