Jenkins version example gives error "TypeError: string indices must be integers" #5

manox · 2022-06-07T20:09:43Z

When running the sync Jenkins version example (https://github.com/pbelskiy/ujenkins#usage) I get the following errror. What am i doing wrong?

Traceback (most recent call last):
  File "/root/test.py", line 8, in <module>
    example()
  File "/root/test.py", line 5, in example
    version = client.system.get_version()

    return self.jenkins._request('GET', '/', callback=callback)
  File "/usr/local/lib/python3.9/dist-packages/ujenkins/adapters/sync.py", line 173, in _request
    self.crumb = self._get_crumb()

Hello! Thanks for bugreport, which version of Jenkins and package are you using?

manox · 2022-06-07T22:01:21Z

Jenkins 2.332.3 and ujenkins 0.3.0

pbelskiy · 2022-06-07T22:55:25Z

@manox I've installed same versions using docker, but all is okay. Could you please add print to 152 line of
/usr/local/lib/python3.9/dist-packages/ujenkins/adapters/sync.py and write here output?

response = self._http_request('GET', CRUMB_ISSUER_URL)
print(response)

And to ``/usr/local/lib/python3.9/dist-packages/ujenkins/core.py` in 43 line

print(response.headers)
if 'application/json' in response.headers.get('Content-Type', ''):

It seems somehow Jenkins returns header without json and it's unpacked from str to json.

Where is your Jenkins server, maybe some proxy is using?

manox · 2022-06-08T09:42:47Z

First of all, thanks for the help. The Jenkins server is local on the network and I access it via a local IP. I used a Jenkins image that I believe has a reverse proxy built in.
Here is the output with the prints.

Edit: I just noticed that it works when attaching the port (8080) to the server address. Problem is therefore solved. Thanks!

pbelskiy · 2022-06-09T10:09:53Z

@manox anyway there is bug in package, it's because of redirect is not processed, could you share please your reverse proxy config of apache?

manox · 2022-06-09T10:22:16Z

OK, sure.

At first it was not possible to install the package from the sources. I had to add the encoding in ujenkins/setup.py in line 18.

with open('README.rst', encoding='utf-8') as readme_file:

Now when I try to reach the server without specifying the port the following happens. Since it is only a local test setup I have not installed an SSl certificate.

Thanks for another issue. About your problem, you can disable ssl check using Jenkins(..., verify=False)

manox · 2022-06-09T16:26:02Z

Thanks, it works when disabling ssl checks.
