How do I mock a binary response?

[drazisil]

I have

mockClient.intercept({
  method: 'GET',
  path: '/v2/exampleOrgName/exampleImageName/blobs/abc123',
}).reply(200, Buffer.from('testGetResponse'), {
  headers: {'content-type': 'application/octet-stream'},
});

The error I'm getting is

Uncaught TypeError: this[kAbort] is not a function
at BodyReadable.destroy (node_modules/undici/lib/api/readable.js:52:19)
at consumeEnd (node_modules/undici/lib/api/readable.js:257:12)
at BodyReadable.<anonymous> (node_modules/undici/lib/api/readable.js:219:7)

at endReadableNT (node:internal/streams/readable:1359:12)
at processTicksAndRejections (node:internal/process/task_queues:82:21)

I'm not sure how to troubleshoot this.

The desired return call is Dispatcher.ResponseData.body.json()

I was close. The correct response is new Response(Buffer.from(JSON.stringify(mockManifest)))

Full code:

mockClient.intercept({
  method: 'GET',
  path: '/v2/exampleOrgName/exampleImageName/blobs/abc123',
}).reply(200, new Response(Buffer.from(JSON.stringify(mockManifest))), {
  headers: {'content-type': 'application/octet-stream'},
});
