errorCode:1, errorMessage: "Invalid signature."

Description/Error
I am trying to test Zoom Web SDK and followed the exact steps stated here: https://marketplace.zoom.us/docs/sdk/native-sdks/Web-Client-SDK/api-reference. However, I still encountered error code: 1, and the error message was “invalid signature.” I did not change the javascript code copied from the Github except for replacing “your API key and secret” with my own.
A friend of mine suggested that maybe I needed to do something with OAuth, but it was not stated in the instructions.

Which Endpoint/s?

Thank you so much for your help!

Hey @szliuxi199908, thanks for posting and using Zoom!

Are you using a JWT App Type for the API key and secret?
