What steps will reproduce the bug?

Try the following code both on chrome & nodejs:

const str = "H4sIAAAAAAAAE0vLzwcAIWVzjAMAAAA=";
const buf = Uint8Array.from(atob(str), c => c.charCodeAt(0));
const ds = new DecompressionStream("gzip");
const writer = ds.writable.getWriter();
writer.write(buf.buffer);
writer.close();
await new Response(ds.readable).arrayBuffer();

How often does it reproduce? Is there a required condition?

For this issue is the function write supposed to work on Buffer | Uint8Array | ArrayBuffer? cc @ronag @VoltrexKeyva

According to the documentation, the function write is not supposed to work on \<ArrayBuffer> in node.(It works in chrome.)

writer.write(buf);

Using \<Uint8Array> is fine.

So, this can be closed?

No, CompressionStream and DecompressionStream are supposed to handle BufferSource, that means, as per how this is done WebCryptoAPI - <ArrayBuffer> | <TypedArray> | <DataView> | <Buffer> should all be valid chunks.

The WPTs for this will soon be enabled #50631.
