How to extract updated XML string from modeler

Developers
1

I am trying to console.log an XML string from modeler – after changes have been made to the model.

I delete some icons, and attempt to get an updated XML string (with deleted icons removed) by calling the following function:

     this.modeler._moddle.toXML(
      this.modeler.definitions,
      { format: true },
      (err, updatedXML) => {
        console.log("updateXML", updatedXML);
      }
    );

updatedXML is undefined

I’m now doing:

  getUpdatedXML = () => {
    return new Promise((accept, reject) => {
      this.modeler._moddle.toXML(
        this.modeler.get("canvas"),
        {
          format: true
        },
        (err, response) => {
          if (err) return reject(err);
          return accept(response);
        }
      );
    });
  };

but getting new error:

Cannot read property 'isGeneric' of undefined
