NetBox version

v3.5.8

Python version

3.10

Steps to Reproduce

We want to setup a git (gitlab on premis) data source.

  1. create a personal access token (all read permissions granted)
  2. setup data source in netbox:
    2.1 URL: https://our-gitlab.com/project.git
    2.2 username: myuser
    2.3 password: (access-token)
  3. Branch: main

The sync erroers out immediately with following error:

09:05:11 default: core.jobs.sync_datasource(job=<Job: 7c7bfb03-a363-433b-ae81-b0f43a4e52c9>) (7c7bfb03-a363-433b-ae81-b0f43a4e52c9)
ERROR:root:Fetching remote data failed (AttributeError): 'NoneType' object has no attribute 'encode'
09:05:12 default: Job OK (7c7bfb03-a363-433b-ae81-b0f43a4e52c9)

Not sure what (AttributeError): 'NoneType' object has no attribute 'encode' means or if its a permission error.
Running netbox on a k8s cluster

Expected Behavior

To be able to fetch the files from the remote git.

Observed Behavior

see above

I have tried also username/password (no token) with the same result

Which user are you running netbox? I faced similar issue with our kubernetes based installation where the user had no name

I have no name!@netbox-c754ff4fd-z99tb:/opt/netbox/netbox$ whoami
whoami: cannot find name for user ID 1000

dulwich requires a username for git. You can either run it with other user which has name or you can set some name as env variable ('LOGNAME', 'USER', 'LNAME', 'USERNAME') https://github.com/jelmer/dulwich/blob/master/dulwich/repo.py#L148

@rasanentimo thanks, that was it.
I've passed extraenvs in the helm chart for the worker node

    worker:
     extraEnvs:
       - name: USERNAME
         value: myusername
       - name: USER
         value: myusername

I wonder though why the username from the data source form doesn't get passed to the git command

Odd that my issue this looks to be the same did not get introduced until 3.6 upgrade. It was working minutes before the upgrade on 3.5.9

From the discussion above, this appears to be related to a configuration issue, so I'm going to close it out. If anyone comes across this and can provide reproduction steps for a stock NetBox deployment, please open a new bug report and reference this one.
