TypeError thrown if http_username and http_password not specified ("NoneType found") #188
Description
It's now impossible to connect to GitLab unless http_username and http_password are explicitly set, even when using token authentication.
This may be a result of a change in the requests Python package, but I'm not sure.
Workaround
A workaround is to set the username and password values to an empty string instead of leaving them unspecified, which results in a value of None internally.
- From a Python program using the library directly, pass
http_username=""andhttp_password=""to the Gitlab class constructor. - From the command-line interface where a
.iniconfig file contains the server URL and authentication token, add two lines to the server configuration section:
http_username=
http_password=
Problematic behavior
With a configuration file guest.ini that has url and private_token defined, but does not have both http_username and http_password, it now fails with an error caused by an exception. This used to work fine.
gitlab-script.py -c guest.ini current-user get
Can't connect to GitLab server (sequence item 0: expected a bytes-like object, NoneType found)
