error 422

[hungtuanz]

Hello
I use nodeJS and I use the latest version of pyroscope nodejs.

When instrumentating my nodejs application, I have this error 422 in the logs of pyroscope.
I tried multiples things but nothing worked, any ideas?

Hi @hungtuanz can you confirm you are using the latest SDK? Can you confirm you are configuring the client as per the documentation? This error message is implying something outside of the SDK is trying to send non-profiling data to the endpoint.
