We encountered this today using the latest (4.11) version.
The culprit is how the URL is parsed. Jenkins requires 3 queryargs:
'json', 'name', and 'type'. But the url part is getting created as a big
dictionary which causes this (truncated for brevity):
https://jenkins.ceph.com/computer/doCreateItem?{'json': ...
When it should really be:
https://jenkins.ceph.com/computer/doCreateItem?json=...
This is caused by:
self.jenkins_open(Request(
self._build_url(CREATE_NODE, params), b''))
Where "params" is a big dictionary of options.
On previous versions where this worked it was actually:
self.jenkins_open(Request(
self.server + CREATE_NODE % urlencode(params)), b'')
Which correctly parses the query args and constructs the URL that
Jenkins is expecting.
