离子4：通过{的代码：5创建文件，消息：“ ENCODING_ERR”}

Question

我正在尝试创建一个新的.xml文件，但由于编码错误而出现错误

请找到以下我尝试过的代码

  this.file.writeFile(this.file.externalApplicationStorageDirectory, "sample.xml",data)
  .then((success)=>{
    console.log("success of xml ",success);
  }, (error)=>{
    console.log("error of xml ", error);
  })
  .catch((error) => {
    console.log("catch error of xml ",JSON.stringify(error));
  })
}```




//Actually i need to create a file xml file I am getting error as {code: 5 , message:"ENCODING_ERR"}
