[NodeJs Upgrading from ADAL to MSAL]: Cannot create property 'authenticationScheme' on string

We are Upgrading from ADAL to MSAL when doing so we are facing issues.

The Code we implemented is

 const msal = require('@azure/msal-node');
  const msalConfig = {
        auth: {
            clientId: config.clientId,
            authority: config.authorityUrl,
            clientSecret: config.clientSecret,
            knownAuthorities: [],
        },
    }
 let cca = new msal.PublicClientApplication(msalConfig);
   const tokenResponse = async function() {
        console.log("callled tokenr response");

        try {
          const response =  cca.acquireTokenByUsernamePassword(config.scopeBase,config.pbiUsername,config.pbiPassword);
          
          return Promise.resolve(response);
        } catch(error) {
  
         return Promise.reject(error);
        }

Can anyone help me how can i fix this issue. Thanks!

acquireTokenByUsernamePassword accepts a single parameter which should be an object with the shape defined here. You are passing in 3 parameters of type string.
