401 Unauthorized Error with Bearer Token Authentication - HomeAssistant with NodeJS

Hello everybody.
I have a HomeAssistant configured with some equipment (Relays), I created the scripts, I can test them and it is working ok.

In Postman I can also access the Script via HTTP to execute the Relays, everything works fine.

But I created an application in Node.Js on the same computer as HomeAssistent, so that Node fires the triggers (executes the scripts and activates the relays), because I want to automate the operation of the scripts based on external data. So far so good, in isolation I can test each action and they are all working.

I am using Bearer Token to authenticate.

But when I make requests through Node.Js, I always get the response “401: Unauthorized”.

I’m using the URL
http://homeassistant.local:8123/api/services/script/turn_on

My POST method header is:

{
   Authorization: "Bearer eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
   Content-Type': "application/json"
}

And the body is:
{ "entity_id" : "script.my_script_name" }

Everywhere I try to call this url with the token and body as above it works fine.
But not with Node.Js, I always get one:

“401: Unauthorized”

Has anyone ever experienced this?

Thank you in advance for reading my problem.
