Tried few calls that work and few which generate errors, but the log does not show log for calls that generate errors:

curl -X POST http://localhost:8056/v1/functions 
  -d '{
	"functionId": "test2", 
	"provider": {
		"type": "awslambda",
		"arn": "arn:aws:lambda:us-east-1:063733696545:function:user-service-prod-test2", 
		"region": "", 
		"accessKeyId": "", 
		"secretAccessKey": ""
	}
}'

# response
{
    "error": "Function doesn't validate. Validation error: \"Missing required fields for AWS Lambda function.\""
}
