Filtering reverse relations against invalid lookups crashes.

from django.db import models


class Author(models.Model):
    name = models.CharField(max_length=10)

class Report(models.Model):
    name = models.CharField(max_length=10)
    creator = models.ForeignKey(Author, models.CASCADE)

>>> Author.objects.filter(report__title="first")
...
  File "/django/django/db/models/expressions.py", line 380, in get_transform
    return self.output_field.get_transform(name)
AttributeError: 'ManyToOneRel' object has no attribute 'get_transform'

In Django 4.1 it raises django.core.exceptions.FieldError: Related Field got invalid lookup: title.
