Mission cancelled because it seems that the ReadableStream between Node.js and DOM is not compatible.

Dom

interface ReadableStream {
    readonly locked: boolean;
    cancel(): Promise<void>;
    getReader(): ReadableStreamReader;
}

Node

    export interface ReadableStream extends EventEmitter {
        readable: boolean;
        read(size?: number): string | Buffer;
        setEncoding(encoding: string): this;
        pause(): this;
        resume(): this;
        isPaused(): boolean;
        pipe<T extends WritableStream>(destination: T, options?: { end?: boolean; }): T;
        unpipe<T extends WritableStream>(destination?: T): this;
        unshift(chunk: string): void;
        unshift(chunk: Buffer): void;
        wrap(oldStream: ReadableStream): this;
        [Symbol.asyncIterator](): AsyncIterableIterator<string | Buffer>;
    }
