@adachenski Is there a publicly accessible endpoint we can use to replicate this issue?

[numaanashraf]

@adachenski could you send us a screen grab of the response headers after this happens?

[adachenski]

@numaanashraf there are no publicly accessible endpoints for the calls that I'm testing
but I'm sending the response headers JPG here

@adachenski This seems to be due to a non-zero Content-Length being sent by the server for 204. Postman would wait for the response from the server (as indicated by the content-length). The request will finally finish when the underlying connection is closed by the client or server. Refer related issue at #2418 (comment) for more details. I'll keep this issue open to discuss how we'ld like to handle such cases.

I've just encountered this as well.

@numaanashraf This indeed seems to happen due to a non-zero Content-Length in reply Header, which in my case is true.
