我已将我的应用程序从角度4升级到角度6.我收到以下错误。错误发生在行返回data.buffer。这是兼容性问题吗?
error TS2322: Type 'ArrayBuffer | SharedArrayBuffer' is not assignable to type 'Arr
ayBuffer'.
Type 'SharedArrayBuffer' is not assignable to type 'ArrayBuffer'.
Types of property '[Symbol.toStringTag]' are incompatible.

serialize(): ArrayBuffer {
let source: ArrayLike<number>[] = this.contents.map(o => new Uint8Array(o));
let lengths = source.map(o => this.numToArr(o.length));
if (!!this.value) {
const bytes = utf8.toByteArray(JSON.stringify(this.value, null, null));
const dataLength = this.numToArr(bytes.length);
source = [bytes, ...source];
lengths = [dataLength, ...lengths];

const totalLength = source.reduce((acc, o) => acc + o.length, 0) + lengths.reduce((acc, o) => acc + o.length, 0);
const data = new Uint8Array(totalLength);
let offset = 0;
source.forEach((item, index) => {
const prefix = lengths[index];
data.set(prefix, offset);
offset += prefix.length;

offset += item.length;
