Exception Type: AttributeError at /plugins/ssot/history/
Exception Value: 'NoneType' object has no attribute 'class_path'

Steps to Reproduce

I do not realy know... I can only give you a lead, which is what I did.

  1. Import jobs using git
  2. Change/move jobs around, resyncing them
  3. Try to access /plugins/ssot/history/
glennmatthews commented 4 months ago

My interpretation here is that SSOT get_source_url() is not accounting for the possibility that there is a JobResult from a Job that has subsequently been uninstalled or deleted.

rifen commented 4 months ago

Ran into this as well, seemed like exactly that. After I had deleted all my not installed apps after a git repo sync then this began to occur in the dashboard and the history. Though the history is giving a <class 'MemoryError'> and the Dashboard is giving me AttributeError: 'NoneType' object has no attribute 'class_path'

Kircheneer commented 4 months ago

Should be a straight-forward fix, to check if the job result exists here:

  File "/opt/nautobot/.local/lib/python3.11/site-packages/nautobot_ssot/models.py", line 137, in get_source_url
    kwargs={"class_path": self.job_result.job_model.class_path},

@dylanbob

nautobot-ssot version: How can I get that? probably 2.6.1

Under Apps -> Installed Apps or with pip show

As for the actual issue, we have found that we are unable to replicate this, at least consistently. Are you able to do this?

dylanbob commented 2 months ago

Hi. My environment changed since I opened this issue, now I have:

I was in 2.6.1 when I opened the issue.

I was able to reproduce the issue right now. Steps :

  1. import a job, using git (in my particular case)
  2. execute the job
  3. delete the job
  4. try to access /plugins/ssot/history/

At 4., the error occurs, here is the traceback:
