client.currentUser() gives an error even though client.login() is successful

[martin-tests]

const client = new TwitterApi({ appKey: process.env.TWITTER_API_KEY, appSecret: process.env.TWITTER_API_KEY_SECRET, accessToken: authToken, accessSecret: authTokenSecret }); let loggedInClientData = await client.login(authVerifier);

So far so good. After this I want to get the user's details:
const additionalInfo = await client.currentUser();

And this gives me the following error:

twitter-api-v2\dist\client-mixins\request-handler.helper.js:103
return new types_1.ApiResponseError(errorString, {
^
