ReCaptcha Enterprise api call always returns score of 0 but the dashboard shows every score has been 0.8 or greater

I created a ReCaptcha Enterprise project for my frontend and am trying to verify assessments in an AWS Lambda.

The ReCaptcha project looks as follows: ReCaptcha Settings

The front end code is a react application but I am just using scripts following the documentation. This all seems to work. I can solve the captcha and get the answer.

const [captchaAnswer, setCaptchaAnswer] = useState<string | null>(null);

useEffect(() => {
    const script = document.createElement('script');

    script.src = "https://www.google.com/recaptcha/enterprise.js";
    script.async = true;
    script.defer = true;

    document.body.appendChild(script);
        
     return () => {
        document.body.removeChild(script);
    }
}, []);


window.reCaptchaCallback = function (response: string) {
    setCaptchaAnswer(response);
};

const submit = () => {
    //Submits the answer to my lambda
}

return (
    <div className="g-recaptcha" data-sitekey="<SITEKEY>" data-callback="reCaptchaCallback" />
);

So next is the lambda which is called as a trigger from Cognito.

const axios = require("axios");

const config = {
  PROJECT_ID: "<PROJECTID>",
  API_KEY: "<APIKEY>", //actually gotten from secret manager
  SITE_KEY:"<SITEKEY>"
};

exports.handler = async (event) => {
  console.log(event);
  
  if (event.triggerSource === "PreSignUp_AdminCreateUser") {
    return event;
  }

  if (!event.request.validationData) {
    throw new Error('Missing validation data');
  }
  
  try {
    const verifyResponse = await axios({
      method: 'post',
      url: `https://recaptchaenterprise.googleapis.com/v1beta1/projects/${config.PROJECT_ID}/assessments?key=${config.API_KEY}`,
      body: {
        event: {
          token: event.request.validationData.token, //I have confirmed this is correctly passed from front end to here
          siteKey: config.SITE_KEY
          expectedAction: "" //Tried it with and without this. Documentation say it isn't being used
        }
      },
      headers: { "Content-Type": "application/x-www-form-urlencoded" }
    });

    console.log(JSON.stringify(verifyResponse.data));
    
    if (verifyResponse.data.score >= 0) {
      event.response.autoConfirmUser = true;
      return event;
    } else {
      throw new Error('Recaptcha verification failed');
    }
  } catch (error) {
    console.error(error);
    throw new Error("Recaptcha verification failed. Please retry");

  }
};

This is the response I always get.

{
    "name": "projects/<PROJECT>/assessments/924d7fc3f0000000",
    "score": 0,
    "reasons": []
}

However the recaptcha dashboard shows that all have the assessments have been >= 0.8 I have no idea what I am doing wrong. thank you for any help.
