Freshdesk CLI "Error while substituting the templates"

@Santhosh, @juventinoromero
Solve the problem as follows:

headers: {
        "Authorization": Basic QmpES1ladkpYbmtDSlo6,
        "Content-Type": "application/json"
      },

After many attempts I decided to get my API KEY and encode it in base64, done that I passed my key in base64 in authorization and it worked. Thank you for all the support and attention in the case.
