'AADSTS900144: The request body must contain the following parameter: 'grant_type'

I am trying to generate the Access_Token after generating the Authorization code using MS Graph API.

I am getting the following error (Screen shot below)

"error_description": "AADSTS900144: The request body must contain the following parameter: 'grant_type'.",

I see that grant_type is present. I checked the rest of the values to be without any spaces. Any ideas on what could be wrong here? I appreciate your support.

Thanks,
