Server error by opening a report: 'list' object has no attribute 'stip'

[maxhandschild]

NetBox version

v3.3.0

Python version

3.8

Steps to Reproduce

I wrote a report in Python and when I ran it, the script just loaded.
When I go back to the overview, I see that the report has run. When I then display the report, the following error appears:

I reduced the report to the problematic lines, then it looks like this:

from extras.reports import Report
from virtualization.models import VirtualMachine

class Test(Report):

  def method():
    srv_list = [ vm.name
      for vm in VirtualMachine.objects.all()
    ]
    return srv_list
  def test_test(self):
    self.log_warning('test',Test.method())

Expected Behavior

I want to get a list of VMs that have previously been filtered for certain attributes.

Observed Behavior

I found a workaround for this issue, but I'm not sure if this causes any problems. So far, my colleagues and I have not been able to identify any problems.
In the file /data/netbox/netbox/utilities/templatetags/builtins/filters.py I made the following changes:

149,161d149
<     schemes = '|'.join(get_config().ALLOWED_URL_SCHEMES)
<
<     # Strip HTML tags
<     value = strip_tags(value)
<
<     # Sanitize Markdown links
<     pattern = fr'\[([^\]]+)\]\(\s*(?!({schemes})).*:(.+)\)'
<     value = re.sub(pattern, '[\\1](\\3)', value, flags=re.IGNORECASE)
<
<     # Sanitize Markdown reference links
<     pattern = fr'\[([^\]]+)\]:\s*(?!({schemes}))\w*:(.+)'
<     value = re.sub(pattern, '[\\1]: \\3', value, flags=re.IGNORECASE)

log_warning() accepts an object and a string. You've passed it an object and a list, hence the exception.

Ok, unfortunately I fail to see that this should be a string. Thanks for the quick help.
