Error getting access token

[pointsnerd]

Hello Devs,

I have followed the instructions to set up the GSheets and Questrade integration and every execution of the code results in and error:

Error getting access token (HTTP 400):
Bad Request

I have replaced the variable refernce YOUR_INITIAL_TOKEN with my Access Token that was generated from Questrade and it throws the error above. I also tried my Refresh Token in the off chance that was what the code was looking for, but I receive the same error.

Any thoughts on how to get around this issue would be most appreciated. Thanks
