TypeError: encoding without a string argument

[niketnishi]

payload_body = request.body
webhook_signature = request.headers['X-Razorpay-Signature']
client = razorpay.Client(auth=(RAZORPAY_KEY, RAZORPAY_PASS))
client.utility.verify_webhook_signature(payload_body, webhook_signature, secret_key)

The above was working fine with python 2.7 but gives an error with python 3.6.12.
As the documentation specifies "Do not parse or cast the webhook request body.:
While generating signature at your end, ensure that the webhook body passed as an argument is the raw webhook request body. Do not parse or cast the webhook request body."

And this gives a TypeError: encoding without a string argument. And when I typecast payload_body to string using str() this throws an exception saying that razorpay.errors.SignatureVerificationError: Razorpay Signature Verification Failed which means the generated sha256 does not match the webhook signature I receive from your end.

Please help to resolve the issue.

@niketnishi
You can resolve your issue in two ways -
body = str(request.body, 'utf-8'). # This will decode the bytes into string
OR
body = json.dumps(request.data, separators=(',', ':'))

@RazorpayTeam - It seems like we are converting the request.body from bytes to string, and then in your code you are just converting it back to bytes. Please remove the double conversion - seems unnecessary.

The first solution gives an error
Razorpay Signature Verification Failed

And the 2nd solution gives an error
Object of type 'bytes' is not JSON serializable

Hi, I can not confirm as currently I am not working on any project which uses Razorpay as payment gateway. Thank You, Niket Nishi
