Hello!

#

What are you specific questions?

dim frost Oct 25, 2021, 10:06 PM

#

hello

#

so the question is this

#

ive set up a webhook using stripe CLI

#

and its working perfectly fine

#

now i trying to set up a webhook using a https url

#

but i keep getting this error message

#

AttributeError at /payments/webhook/
'NoneType' object has no attribute 'type'

#

im using python / Django

#

i understand the error message

#

but im not sure why im getting it

#

as this is the same code i've used

#

when i use the webhook via the stripe CLI

rain abyss Oct 25, 2021, 10:10 PM

#

Can you share the code that's throwing that error?

dim frost Oct 25, 2021, 10:10 PM

#

sure

#

once second

#

@csrf_exempt
@api_view(['POST'])
@permission_classes([AllowAny])
def webhook(request):
payload = request.body
sig_header = request.META['HTTP_STRIPE_SIGNATURE']
event = None

try:
event = stripe.Webhook.construct_event(
payload, sig_header, endpoint_secert
)

except ValueError as e:

Invalid payload

Can you edit your message and put that in a code block with indentation? You can use three backticks (```) to start and end a code block.

dim frost Oct 25, 2021, 10:12 PM

#

sure

#

@csrf_exempt
@api_view(['POST'])
@permission_classes([AllowAny])
def webhook(request):
payload = request.body
sig_header = request.META['HTTP_STRIPE_SIGNATURE']
event = None

try:
    event = stripe.Webhook.construct_event(
        payload, sig_header, endpoint_secert
    )

except ValueError as e:
    # Invalid payload
    return Response(status=status.HTTP_400_BAD_REQUEST, data={"message": "invaild Payload"})
    
except stripe.error.SignatureVerificationError as e: 
    # Invalid signature
    return Response(status=status.HTTP_400_BAD_REQUEST, data={"message": "invaild Payload"})
    
except AttributeError as e:
    # pass
    return Response(status=status.HTTP_400_BAD_REQUEST, data={"message": "Attribute Error {}".format(e)})

#

is that better

#

?

rain abyss Oct 25, 2021, 10:16 PM

#

Yep, that's easier to read.

dim frost Oct 25, 2021, 10:16 PM

#

ok

#

sorry i dont know how to use the three back tickets

rain abyss Oct 25, 2021, 10:17 PM

#

On your keyboard, the key to the left of the 1 key. If you type that three times you can then write multiline code.

#

For example, like this:

@csrf_exempt
@api_view(['POST'])
@permission_classes([AllowAny])

#

This is how I wrote that:

\`\`\`python
@csrf_exempt
@api_view(['POST'])
@permission_classes([AllowAny])

#

Err, without the backslashes.

dim frost Oct 25, 2021, 10:18 PM

#

oh ok

rain abyss Oct 25, 2021, 10:19 PM

#

Which line of that code you shared is throwing the "AttributeError at /payments/webhook/ 'NoneType' object has no attribute 'type'" error?

dim frost Oct 25, 2021, 10:19 PM

#

so at the moment i'm handling that error message

#

by using the

#

except AttributeError as e:
        # pass
        return Response(status=status.HTTP_400_BAD_REQUEST, data={"message": "Attribute Error {}".format(e)})

#

without this line

#

that error message will appear

rain abyss Oct 25, 2021, 10:23 PM

#

Can you log out the values for payload and sig_header and make sure they're being set correctly?

dim frost Oct 25, 2021, 10:24 PM

#

ok sure

#

let me try that

#

this might take me a few minutes as i need to re-upload code into the cloud

dim frost Oct 25, 2021, 10:45 PM

#

hello again

#

i've got the output

#

#

thats the output from the object that been populated with data

worldly cedar Oct 25, 2021, 10:53 PM

#

So we can't do much with the payload, we can't verify it for you. Rubeus was simply trying to make sure you had values in them

dim frost Oct 25, 2021, 10:54 PM

#

ok

worldly cedar Oct 25, 2021, 10:55 PM

#

Unfortunately, this means something is changing the data/payload somewhere in your stack. It can be extremely painful to debug this but that's what you need to track down

dim frost Oct 25, 2021, 10:55 PM

#

oh right

#

so its on my side then

worldly cedar Oct 25, 2021, 10:56 PM

#

it's hard to say. What is your stack? Usually it means something on your end is "tampering" with the raw body we send you

dim frost Oct 25, 2021, 10:57 PM

#

so im using azure webapp

#

to host my python django rest framework app

worldly cedar Oct 25, 2021, 10:58 PM

#

Have you first made this work locally?

dim frost Oct 25, 2021, 10:58 PM

#

yes

worldly cedar Oct 25, 2021, 10:58 PM

#

okay so it works fine locally and doesn't on your host?

dim frost Oct 25, 2021, 10:58 PM

#

i was using stripe cli

#

and it works fine

#

now i've tried setting up the webhook using the https url

#

im getting this error message

worldly cedar Oct 25, 2021, 11:00 PM

#

hum that's strange if it's the same code, it should just work. But like I was saying it can be really painful to debug 😦

dim frost Oct 25, 2021, 11:01 PM

#

i think i may know what the problem is

worldly cedar Oct 25, 2021, 11:01 PM

#

oh that's good to hear!

dim frost Oct 26, 2021, 12:01 AM

#

Hi

#

so i've fixed it

#

you was right

#

there was a problem on my end

#

i was using the Signing secret that the CLI had provided me

worldly cedar Oct 26, 2021, 12:03 AM

#

ohhhhhh

dim frost Oct 26, 2021, 12:03 AM

#

which was wrong

#

lol

worldly cedar Oct 26, 2021, 12:03 AM

#

nice that it wasn't a "raw payload issue" and was just the secret, I should have asked you to double check

#

it's so hard to debug those 😦

dim frost Oct 26, 2021, 12:04 AM

#

yeah

#

once i was able to output the error message properly

#

i could see the problem

#

Thank you for the support

worldly cedar Oct 26, 2021, 12:15 AM

#

Glad you got unblocked, congrats 🙂
