Errors in Lightning Experience

Available in: Lightning Experience

First, there are “expected” errors, such as a validation error for a form field, or a feature configuration that isn’t possible. When you encounter these kinds of errors, they’re usually accompanied by explanations in the user interface. The explanation tells you what’s wrong, and often how to fix it.

As a Salesforce admin, when you run into these errors, if the error message doesn’t provide enough information, consult Salesforce Help.

You can access Salesforce Help directly from the Lightning Experience header (1). The "Help for this Page" option (2) is available in both Lightning Experience and Salesforce Classic.

If you’re an end user, we encourage you to try Salesforce Help. But don’t hesitate to reach out to your Salesforce admin if the answers aren’t easy to find.

• View Errors in Error Windows
  Before Spring ’26, and by default, Lightning Experience shows runtime errors in an error window.
• View Errors in the Error Console
  When enabled, the Error Console captures and shows component and page errors without interrupting your work in Salesforce. The console collects non-fatal errors so you can see them when it’s convenient for you, and they don’t require interaction. Fatal errors still show in error windows that you must dismiss before continuing. The Error Console also collects fatal errors for later inspection.
• Enable the Error Console in Setup
  Enable or disable the Error Console for your users. The console collects warnings and non-fatal errors so you can see them when it’s convenient, instead of being an interruption. The Error Console setting applies to all users of your org.
