I am creating a aws API Gateway to call my Lambda function. I have created an authentication key that is checked in the lambda function I created but I keep getting this error: {auth_token} not a valid key=value pair (missing equal-sign) in Authorization header: Bearer {auth_token}. I am calling the api function through axios using this:

I have no idea why I am receiving this response because the request data matches the model… Additionally, when I manually configure and run a test on my Lambda function, everything works fine… What am I overlooking here?
