Exception trying to add a custom script

[peteeckel]

Deployment Type

Self-hosted

NetBox Version

v4.0-beta1

Python Version

3.11

Steps to Reproduce

1. Create a file with this content:

from extras.scripts import Script


class Test(Script):

    class Meta:
        name = "Test"
        description = "This is a test script without any function"
        commit_default = True

    def run(self, data, commit):
        self.log_info("Script was executed")

2. Go to the NetBox GUI and navigate to 'Customization/Scripts/Add' to add the script
3. Go to 'Upload File/Choose File' and select the local file with the script for upload, then click 'Create'

Expected Behavior

The script is added to the list of installed scripts. This works perfectly in v3.7.5.

Observed Behavior
