Port number was not identified. httpx api has changed.


httpx api has changed

I've upgraded to the latest version of eikon 1.1.6.post2 in order to solve a separate issue. However, I get the error Port number was not identified.

After doing some digging I've narrowed it to the check_port method:

In [1]:
APP_KEY = "..."
In [2]:
import logging
import eikon as ek

logger = logging.getLogger("pyeikon")
logger.setLevel(5)

desktop_session = ek.streaming_session.desktop_session.DesktopSession(APP_KEY)
await desktop_session.check_port(9000)
desktop_session._check_port_result

2020-09-24 15:02:27,834 P[23284] [MainThread 1104] Send GET request to http://localhost:9000/api/status to detect API Proxy...
2020-09-24 15:02:27,840 P[23284] [MainThread 1104] Error on checking port 9000 : AttributeError("'Request' object has no attribute 'prepare'",)

Calling http_request_async

Out[2]:
False

Within the eikon package I've also printed the _http_request object on line 630 of eikon.streaming_session.session.Session.

_http_request is an instance of httpx.Request. However, the api for this has changed and the prepare method has been made private as _prepare.

Note that the call to _http_request.prepare() will now throw an attribute error (as I am getting). I imagine that the devs will want to take a look and make changes as required (or lock the httpx dependency to a version that worked).

Thanks, Simon.

Hi,

You're right, we detected yesterday a breaking change in httpx and we'll published soon a fix.
In the meantime, you can downgrade httpx to 0.14.2 as a workaround (pip install httpx==0.14.2)
