Workers zlib failure when trying to gunzip data

Example code for 2. is:

const object = await env.BUCKET.get(key);
const blob = await object.blob();
const tmp_array = new Uint8Array(await blob.arrayBuffer());
const data = zlib.gunzipSync(Buffer.from(tmp_array));

const object = await env.BUCKET.get(key);
const blob = await object.blob();
const tmp_array = new Uint8Array(await blob.arrayBuffer());
const data = zlib.gunzipSync(Buffer.from(tmp_array));

Ends up with:
