bpmnModeler.importXML Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'error')

根据引用和引用的代码，出现错误Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'error')是因为在创建新的Diagram时，可能存在一些问题导致无法正确读取error属性。在引用中对代码进行了修改，使用了async和await来处理异步操作，这可能会解决这个问题。在修改后的代码中，通过使用try-catch语句捕获错误，并将错误信息打印到控制台。因此，您可以将代码改为如下所示来避免错误的发生：

async createNewDiagram() {
  try {
    const result = await this.bpmnModeler.importXML(xmlStr);
    const { warnings } = result;
    console.log(warnings);
    this.success();
  } catch (err) {
    console.log(err);
  }
},

这样修改后，如果在导入XML时出现错误，错误信息将被正确地捕获并打印到控制台，避免了出现Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'error')的情况。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
