Django Q Bad Signature

[ropraet]

Hello,

I updated the version from Django Q to the newest one, and suddenly I am getting:

Message: BadSignature('Signature "rQv3sSym58u1EYYibwMnKOgY43o" does not match',)
Arguments: ('Traceback (most recent call last):\n File "/usr/local/lib/python3.6/dist-packages/django_q/cluster.py", line 351, in pusher\n task = SignedPackage.loads(task[1])\n File "/usr/local/lib/python3.6/dist-packages/django_q/signing.py", line 26, in loads\n obj, key=Conf.SECRET_KEY, salt=Conf.PREFIX, serializer=PickleSerializer\n File "/usr/local/lib/python3.6/dist-packages/django_q/core_signing.py", line 40, in loads\n base64d = force_bytes(TimestampSigner(key, salt=salt).unsign(s, max_age=max_age))\n File "/usr/local/lib/python3.6/dist-packages/django_q/core_signing.py", line 75, in unsign\n result = super(TimestampSigner, self).unsign(value)\n File "/usr/local/lib/python3.6/dist-packages/django_q/core_signing.py", line 60, in unsign\n raise BadSignature('Signature "%s" does not match' % sig)\ndjango.core.signing.BadSignature: Signature "rQv3sSym58u1EYYibwMnKOgY43o" does not match\n',)

What is wrong here? Thanks!

Seeing the same error now. Let me add the traceback I am getting:

Hello,

I change the secret key with one generate like this :

python -c "import secrets; print(secrets.token_urlsafe())"

tips from : georgemarshall/django-cryptography#33 (comment)

Works for me.

Best,

[amo13]

Oh, forgot about this one.
For me, the issue is resolved: I didn't notice that I was feeding a wrong configuration file to my django app (precedence was unexpectedly taken by another file than the one I thought). Feeding the right config file to the application solved the bad signature issue of which I pasted my logs above.

I am getting same issue when trying to run async_task
File "/usr/local/lib/python3.7/site-packages/django_q/tasks.py", line 71, in async_task return _sync(pack) File "/usr/local/lib/python3.7/site-packages/django_q/tasks.py", line 762, in _sync task = SignedPackage.loads(pack) File "/usr/local/lib/python3.7/site-packages/django_q/signing.py", line 26, in loads obj, key=Conf.SECRET_KEY, salt=Conf.PREFIX, serializer=PickleSerializer File "/usr/local/lib/python3.7/site-packages/django_q/core_signing.py", line 35, in loads base64d = force_bytes(TimestampSigner(key, salt=salt).unsign(s, max_age=max_age)) File "/usr/local/lib/python3.7/site-packages/django_q/core_signing.py", line 70, in unsign result = super(TimestampSigner, self).unsign(value) File "/usr/local/lib/python3.7/site-packages/django_q/core_signing.py", line 55, in unsign raise BadSignature('Signature "%s" does not match' % sig) django.core.signing.BadSignature: Signature "GWJCifsA-4w2KiT8yKQVx-GY0HE" does not match

The solution to update SECRET_KEY did not work for me

[tboulogne]

@luk8475 did you generate a safe url SECRET_KEY ?

[luk8475]

@tboulogne Yes, I ran python -c "import secrets; print(secrets.token_urlsafe())" and updated my settings, but it did not work

[daviddavis83]

I am having the same issue when using async_task.

[samdixonbrown]

I'm also having the same issue and token_urlsafe() doesn't seem to help

[amo13]

This project is abandoned. Last commit is more than a year ago.

[samdixonbrown]

@amo13 Ok thanks. When you said:

Oh, forgot about this one. For me, the issue is resolved: I didn't notice that I was feeding a wrong configuration file to my django app (precedence was unexpectedly taken by another file than the one I thought). Feeding the right config file to the application solved the bad signature issue of which I pasted my logs above.

By "feeding a wrong configuration file" you mean your settings.py?

[amo13]

That was with paperless. There are 3 locations on the filesystem where you can place the paperless.conf configuration file. I placed it under /etc/paperless.conf. When launching paperless, it looks under ./paperless.conf first before looking at /etc/paperless.conf if the first one does not exist. After upgrading paperless, a template configuration file is placed in the first location, taking precedence over my real configuration file, which in turn is not read at all. This is what caused the Bad Signature error for me.
