TypeError: encoding without a string argument for razorpay webhook secret verification error

I am trying verify if the webhook came from Razorpay but getting following error.

TypeError: encoding without a string argument

Here is the code:

webhook_secret = MY_WEBHOOK_SECRET
signature = request.headers['X-Razorpay-Signature']
jsondata = json.loads(request.body)
client = razorpay.Client(auth=(MY_KEY, MY_SIGNATURE))
verify = client.utility.verify_webhook_signature(jsondata, signature, webhook_secret)

I'm getting error in the last line. Can someone help me with this? Thanks!

For Django it's not really required to convert the request body to json and back to string. This process kept giving me signature verification error. Just decoding the body will do the trick. So the code is as follows:

webhook_secret = MY_WEBHOOK_SECRET
signature = request.headers['X-Razorpay-Signature']
body = request.body.decode()
client = razorpay.Client(auth=(MY_KEY, MY_SIGNATURE))
client.utility.verify_webhook_signature(body, signature, webhook_secret)

This worked for me. Please check this answer and this issue for reference.

webhook_secret = MY_WEBHOOK_SECRET
signature = request.headers['X-Razorpay-Signature']
jsondata = json.loads(request.body)
client = razorpay.Client(auth=(MY_KEY, MY_SIGNATURE))
client.utility.verify_webhook_signature(json.dumps(jsondata, separators=(',', ':')), signature, webhook_secret)

This is working for me.
