Thanks for this report, we will investigate this cc @sentaur-athena

This issue is fixed now. We investigated and the reason was a new json serializer we started using since May 9. We reverted the changes to the previous serializer and looking at dashboards the 400 and 401 responses are eliminated.

@quintasda as we're adding back the new serializer wanted to make sure we're not breaking customer's experience. Can you please provide me with code snippet of how you're validating signature?

You mentioned Verify the Signature from our docs but I was wondering if you're using the python or js example? Also what you use to dump json.
