There was a problem hiding this comment.
This line breaks Express' flow control. Indeed, when the stream is being consumed, the consumer might will also catch that error. The consumer can then decide to do multiple things:
- call
next()ornext(err) - handle the error and write to the response
in any case, the error listener here will not "abort" the request, but only trigger the next error middleware, and will cause that error middleware to be called while the body consumer might try to do stuff with the response.
