Unable to access "changes" menu. Cannot read properties of null (reading 'firstName')

We get this message: Sorry, but something went wrong. Our team has been notified and we are investigating. Event Id: 7cc9a9461ceb4cbc834ccec41ab8d0e5. TypeError: Cannot read properties of null (reading 'firstName') Wondering if the reason is that none of our 3 suscribers have that field populated?

Answer The error you're encountering, "Cannot read properties of null (reading 'firstName')," likely occurs because one or more of your subscribers do not have their firstName field populated. This can lead to issues if the code expects this field to always have a value. To resolve this, ensure that all your subscribers have the firstName attribute set. You can check and update the subscribers' information using code similar to the following:

import { Novu } from '@novu/node';
const novu = new Novu('<YOUR_NOVU_API_KEY>');

await novu.subscribers.update('<SUBSCRIBER_ID>', {
  firstName: 'John', // Provide a valid firstName
  // other fields you want to update
});

import { Novu } from '@novu/node';
const novu = new Novu('<YOUR_NOVU_API_KEY>');

await novu.subscribers.update('<SUBSCRIBER_ID>', {
  firstName: 'John', // Provide a valid firstName
  // other fields you want to update
});

(1) Additionally, verify that your subscribers have the necessary fields populated by checking their attributes in the Novu dashboard.
