Serverless deploy on AWS - routes brakes - node.js

Question

I'm deploing my first nodejs serverless app on AWS. In local stage all work well, but when I try to access to my app on AWS, all the routes are brakes. The endpoint serving from the cli is like this:
https://test.execute-api.eu-west-1.amazonaws.com/stage/
adding the word stage at the end of the path. So all my routes to static resources or other endpoint are brakes.
This is my config file:
secret.json
{
"NODE_ENV": "stage",
"SECRET_OR_KEY": "secret",
"TABLE_NAME": "table",
"service_URL": "https://services_external/json",
"DATEX_USERNAME": "usrn",
"DATEX_PASSWD": "psw"
}
serverless.yml
service: sls-express-dynamodb
custom:
iopipeNoVerify: true
iopipeNoUpgrade: true
iopipeNoStats: true
secrets: ${file(secrets.json)}

DATEX_PASSWD: ${self:custom.secrets.DATEX_PASSWD}
DATEX_URL: ${self:custom.secrets.DATEX_URL}

You should be able to find out the API Gateway endpoint via Web UI.
Login into the AWS Console
Go to API Gateway
On the left panel, click on the API name. (E.g. sls-express-dynamodb-master)
On the left panel, click on Stages
On the middle panel, click on the stage name. (E.g. master)
On the right panel you will find the API URL, marked as: Invoke URL
