Errors during training sessions can differ based on their source, Nicole. Sharing details about the particular message or code will allow us to assist you more effectively.
Also, could you specify which section in QuickBooks Online (QBO) you encountered it in? Additional information is much appreciated.
However, if you're encountering a null-type or a bad gateway error, we can perform a browser troubleshooting step to eliminate them. It will discard potentially corrupt or outdated stored data and fetch fresh, correct information from the server.
To begin, clear your browser's cache and cookies for a fresh start. Including cookies will sign you out of your account. With this, you can sign in to your account again and proceed to the training you are currently in. Aside from that, you can use other supported browsers if you have one for a better experience.
