Nothing happen inside of an async function (send request with easysoap) - node.js

Question

I am new in node.js, and I am experimenting things since a few days already.
Today, I have tried to send a XML request to an API, with the use of easysoap-request.
It worked perfectly, but I would have had to create an XML file for each different query, so I tried with easysoap. Here my code:
const EasySoap = require('easysoap');
console.log("test");
(async () => {
const params = {
host : 'https://comeapi.com',
path : '/dir/soap',
wsdl : '/dir/wsdl',
headers: [{
'user-agent': 'Request-Promise',
'Content-Type': 'text/xml',
}]
}
var soapClient = EasySoap(params);
soapClient.call({
method :'one_methode',
attributes: {
xmlns: 'https://someapi.com'
},
params: {
'api' : {
'authentication' : {
'login' : 'mylogin',
'password' : 'mypassword'
},
'params' : {
'another_params' : {
'name' : 'Brian',
}
}
}
}
}).then((callResponse) => {
console.log(callResponse.data); // response data as json
console.log(callResponse.body); // response body
console.log(callResponse.header); //response header
}).catch((err) => {
throw new Error(err);
});
console.log("test2");
});
console.log("test3");
When I'm starting my file with the node command, it's only shows me "test" and "test 3" in the terminal, instead of the response of the API.
I do not understand the problem in my program because I have already used the "(async () => {" function in previous programs, and that rather well worked.
Thanks for you're help. ^^
Edit: I added the missing part in my code and now there is something new. It's an error, and I don't understand it...
(node:10264) UnhandledPromiseRejectionWarning: Error: Error: no wsdl/xml response
at soapClient.call.then.catch (C:\Users\user\Documents\src\script.js:40:15)
at process._tickCallback (internal/process/next_tick.js:68:7)
(node:10264) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). (rejection id: 1)
(node:10264) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
Is this a problem with the .catch() ? Can someone explain me ?
Thanks

Answer 1

Your function is only defined but never called. Call your function at the end of the definition
(async () => {
....
console.log("test2");
})(); // call this function by adding this parenthesis
This is called a IFFY(Immediately-Invoked Function Expression) function in javascript
If you don't want to use a IFFY name your function and call it, like this
const f = async () => {
....
console.log("test2");
}
f()

Answer 2

Your async function needs to be called. Currently you are only declaring a function. To execute it, you need to replace the line before console.log("test3"); by })();
