DoesNotExist exception during persistent share setup

[max-uni-hd]

Describe the bug
When trying to set up persistent sharing I get this error here, when I insert the tag persistent_share_table in a template:

DoesNotExist at /targets/6/share/

ContentType matching query does not exist.

Request Method: 	GET
Request URL: 	http://localhost:8000/targets/6/share/
Django Version: 	5.2.15
Exception Type: 	DoesNotExist
Exception Value: 	

ContentType matching query does not exist.

Exception Location: 	/usr/local/lib/python3.11/site-packages/django/db/models/query.py, line 635, in get
Raised during: 	tom_targets.views.TargetShareView
Python Executable: 	/usr/local/bin/python
Python Version: 	3.11.15
Python Path: 	

['/galactic_science_opm',
 '/usr/local/lib/python311.zip',
 '/usr/local/lib/python3.11',
 '/usr/local/lib/python3.11/lib-dynload',
 '/usr/local/lib/python3.11/site-packages']

This is the function for the tag:

@register.inclusion_tag('tom_targets/partials/persistent_share_table.html', takes_context=True)
def persistent_share_table(context, target):
    """
    Returns a partial for a table of persistent shares, used in persistent share management forms
    """
    request = context['request']
    persistentshares = get_objects_for_user(request.user, f'{Target._meta.app_label}.view_persistentshare')
    if target:
        persistentshares = persistentshares.filter(target__pk=target.pk)
    can_delete = request.user.has_perm(f'{Target._meta.app_label}.delete_persistentshare')
    return {'persistentshares': persistentshares, 'target': target, 'can_delete': can_delete}

And this is the line that causes the exception:

persistentshares = get_objects_for_user(request.user, f'{Target._meta.app_label}.view_persistentshare')

Could this have something to do with the fact that we use a custom target that extends BaseTarget?
Similar to this bug report(#1538) ?

To Reproduce
Steps to reproduce the behavior:

1. Clone https://github.com/LSST-TVSSC/galactic-science-opm/tree/feature/78-share-data-to-MOP
2. Add template tag persistent_share_table to tom_targets/target_share.html
3. Try sharing a target
4. See error above.

Expected behavior
Setting up persistent sharing should be possible.

Additional context
This happens on tomtoolkit 3.0.0alpha12

I was running into the same exception last week even when testing normal, non-persistent sharing. I'll dig into it further. In the meantime:
