Why is the condition in this rule firing every time?

I only want this to fire if there is no value for user.app_metadata.paid_account but it is firing and updating every time a user logs in even if they already have this value!

This previously worked fine.

function (user, context, callback) {
  user.app_metadata = user.app_metadata || {};

  if (!user.app_metadata.paid_account) {
    user.app_metadata.paid_account = false;
    var date = new Date();
    user.app_metadata.trial_end_date = date.setDate(date.getDate() + 7);
    auth0.users.updateAppMetadata(user.user_id, user.app_metadata)
        callback(null, user, context);

@dylan can you clarify the following:

  1. How have you verified that this is firing? Have you used the Realtime webtask logs extension, with console.log() outputs within the code block?
  2. Are you calling the callback anywhere outside of the if statement?
  3. Do you have any Hooks that may be populating the user.app_metadata.paid_account?

You’re applying a logical NOT operator to the expression user.app_metadata.paid_account. The expression will be falsy when the property is undefined, but also for: null, false, -0, +0, NaN, “”.

Since you’re then setting the property to false, next iterations will still trigger the condition because the falsy value is inverted to a truthy value by the logical NOT operator. If you only want to execute the body of the condition when the property is not yet defined you should instead use:

if (user.app_metadata.paid_account === undefined) {
    // ....
