UnicodeDecodeError on journalctl log
chiara-paci opened this issue · comments
When django raise a 500 error (f.e. following a ValueError), instead of exception stacktrace on journalctl log there is an UnicodeDecodeError.
Environment: Debian 10.12, Python 3.7.3, Django 3.2.5, Daphne 3.0.2, Apache 2.4.38

Sample output
In a queryset, I define an annotation with the same name as a field:
class FoodDiaryEntryManager(models.Manager):
def get_queryset(self):
qset=models.Manager.get_queryset(self)
return qset.annotate(
qta=models.F("quantity")*models.F("measure_unit__factor"),
ratio=models.F("quantity")*models.F("measure_unit__factor")/100
).annotate(
kcal=models.F("ratio")*models.F("product__kcal")
)
class FoodDiaryEntry(models.Model):
...
product = models.ForeignKey(Product,on_delete=models.PROTECT)
measure_unit = models.ForeignKey(MeasureUnit,on_delete=models.PROTECT)
quantity = models.FloatField(validators=[validators.MinValueValidator(0.0)])
...
kcal = models.FloatField(editable=False)
...
objects = FoodDiaryEntryManager()
The expected behaviour on journalctl log is an exception stacktrace with something like (from django console):
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "/usr/local/lib/python3.7/dist-packages/django/db/models/query.py", line 1091, in annotate
return self._annotate(args, kwargs, select=True)
File "/usr/local/lib/python3.7/dist-packages/django/db/models/query.py", line 1126, in _annotate
"the model." % alias)
ValueError: The annotation 'kcal' conflicts with a field on the model.
Instead I have:
# journalctl -f -u daphne-baskerville.service
...
