I think it may be more appropriate to add Buffer | stream.Readable to the ResponseError union type. @restrry WDYT?

When it's required? As I can see proxyRequest rejects a promise with an error message, not steam or a buffer

kibana/src/plugins/console/server/lib/request.ts

Line 92 in 0e8fae1

const onError = (e: Error) => reject(e);

Hey @restrry ! Thanks for weighing in!

This is the flow:

User issues request in browser -> console streams to ES -> ES responds (e.g., status code 400!) -> console streams back to browser -> user sees error.

With the current implementation console cannot stream the error response ES gave us back to browser because the current implementation wants to send back JS object encoded as JSON when we haven't read the body into memory for that.

The error handler you linked to is for lower-level errors on http request - like if the socket gets hung up. Not for a 4xx or 5xx status code. You can see here how the response is handled:

kibana/src/plugins/console/server/routes/api/console/proxy/create_handler.ts

Line 166 in 541ecf5

esIncomingMessage = await proxyRequest({

Ok, I think we can merge the current changes. Could you add headers configuration as done in https://github.com/elastic/kibana/pull/55690/files/46c5cab221d6b63a8b442f3ba8a3a7bdc4c03f4d#diff-92d94ad4d163809567c4258f95ff37e2R96 ?

agree, can be done in #56305

const { payload } = kibanaResponse;

// Special case for when we are proxying requests and want to enable streaming back error responses opaquely.
if (Buffer.isBuffer(payload) || payload instanceof stream.Readable) {
return this.responseToolkit.response(payload).code(kibanaResponse.status);
}

// we use for BWC with Boom payload for error responses - {error: string, message: string, statusCode: string}
const error = new Boom('', {
statusCode: kibanaResponse.status,
