I am a new user and I am just exploring how the API is working. After reading the documentation, I tried to place a simple buy order (Referenced the documentation of the python client and API ) I am able to authenticate myself and all other methods on the kite object seem to work fine, however when placing an order I get the below message. Invalid `api_key` or `access_token` I double checked my API key and generated a fresh access_token multiple times however the issue persists. Could someone please suggest what I may be doing wrong here or how to go about debugging this issue ?
