Procedure processCheckOut not present

[Edijae]

I'm trying to call a method but the data that I'm getting is Procedure 'processCheckOut' not present

` var params = { "host": 'bla bla', "path": '/bla bla.php', "wsdl": '/bla bla.php?wsdl', headers: soapHeader};

const soapClient = EasySoap(params, { secure: true });

soapClient.getAllFunctions()
    .then((functionArray) => { console.log(functionArray); })
    .catch((err) => { throw new Error(err); });

soapClient.getMethodParamsByName('processCheckOut')
    .then((methodParams) => {
        console.log("METHOD PARAMS ARE \n "+JSON.stringify(methodParams)+"\n\n");
    })
    .catch((err) => { throw new Error(err); });

soapClient.call({
    method: 'processCheckOut',
    params: args
}).then((callResponse) => {
    console.log("DATA IS --------- " + JSON.stringify(callResponse.data));	// response data as json
    console.log("BODY IS--------- " + callResponse.body);	// response body
    console.log("HEADER IS--------- " + callResponse.header);  //response header
}).catch((err) => { console.log("processCheckout error: " + err) });

`

getAllFunctions() and getMethodParamsByName() returns successfully but soapClient.call() returns procedure not present when logging out data console.log("DATA IS --------- " + JSON.stringify(callResponse.data));

DATA IS --------- {"Fault":{"faultcode":"SOAP-ENV:Server","faultstring":"Procedure 'processCheckOut' not present"}}
