Textract AnalyseId not working / available on Lambda

Is it possible that the new Textract AnalyzeID function is not available in Lambda yet? In both Lambda and SAM I get this error:

Textract.analyzeID is not a function

const AWS = require('aws-sdk');
const Textract = new AWS.Textract();

exports.handler = async (event, context) => {
      Textract.analyzeID(params, function(err, data) {
        ...
      });
};

When I run the similar code in an empty project locally it works, making me wondering if its something to do with the Lambda/SAM container?
