解析tiff格式图片报错

[collaborator-one]

tifToImg(path) {
console.log('-----------------');
// path = 'https://datacenter1-oss.oss-cn-shenzhen.aliyuncs.com/ifi_pic/EP/0016/268/EP0016268B1/zy/000001.tif'
path = '../../assets/000001.tif'
// var Tiff = require('tiff.js')
// console.log(Tiff);
// let imgBox = this.$refs.imgBox
var xhr = new XMLHttpRequest();
xhr.responseType = 'arraybuffer';
xhr.open('GET', path);
xhr.onload = (e) => {
// console.log(e);
var tiff = new Tiff({buffer: xhr.response});
var url = tiff.toDataURL()
console.log(url);
return url
// let img = document.createElement('img')
// img.src = url
// img.style.width = width + 'px'
// img.style.height = height + 'px'
// container.append(img)
};
xhr.send();
},

代码中var tiff = new Tiff({buffer: xhr.response});这句话报错如下
Uncaught TypeError: Cannot read property 'slice' of null
