Aws-sdk dynamo db doesn't execute query in rules

I am having difficulty to execute an aws-sdk dynamodb api call within auth0 RULEs, which otherwise worked in ACTIONs and HOOKs. Since ACTIONs do not fire pre-registration, and HOOKs don’t work work for social logins, the last resort is to use RULEs.

Does anyone have experience with executing aws-sdk dynamoDB queries from Auth0 rules? Can someone point out what am I doing wrong in the following snippet?

function(user, context, callback) {
  const AWS = require('aws-sdk@2.458.0');

var db = new AWS.DynamoDB({
    accessKeyId: configuration.AWS_KEY_ID, 
    secretAccessKey: configuration.AWS_SECRET, 
    region: configuration.AWS_REGION

const run = async () => {
    try {
      console.log("before call await list tables...");
      const results = await db.listTables({}).promise();
      console.log("we should have a result here...");
    } catch (err) {
      console.log("or some sort of error thrown:", err);
  return callback(null, user, context);

best wishes: steve
