Repro steps.

Proxy a request to a backend server which uses the 'transfer-encoding: chunked' strategy

The log given by the failure.

[HPM] Error occurred while trying to proxy request /api/backend/content from localhost:4200 to http://localhost:4444 (HPE_UNEXPECTED_CONTENT_LENGTH) (https://nodejs.org/api/errors.html#errors_common_system_errors)

Desired functionality.

I think this is related to a bug in the express-http-proxy

villadora/express-http-proxy#47

I want to know if the version of the express proxy used by angular-cli contains the fix above

Mention any other details that might be useful.

The CLI just passes on the proxy options to https://github.com/webpack/webpack, that would be a better place to open an issue like this one. To know the version of express-http-proxy installed in your project, you can do npm list express-http-proxy.
