Introduction

Errors are inevitable in complex Salesforce applications—but constant pop-ups and interruptions aren’t. With the Spring ’26 preview release, Salesforce introduces the Error Console, a new way to capture and review page and component errors without breaking user workflows.

The Error Console quietly collects errors in the background, allowing users to continue working while still giving admins and developers the information they need to troubleshoot effectively.

What Is the Error Console?

The Error Console is a centralized panel in Lightning Experience that:

● Collects non-fatal page and component errors
● Stores fatal errors after they appear in modal dialogs
● Displays error details for later inspection
● Eliminates unnecessary interruptions during daily work

Instead of breaking your flow, Salesforce lets you review errors when it’s convenient.

Why This Feature Matters - Before Spring ’26

● Non-fatal errors often appeared as alerts or interruptions
● Users had to stop working to acknowledge errors
● Sharing error details with admins was difficult

With the Error Console

● Non-fatal errors don’t interrupt users
● Errors are captured automatically
● Error details are easy to share
● Faster troubleshooting

Fatal vs Non-Fatal Errors (Quick Overview)

Non-Fatal Errors
● Collected silently
● Logged in the Error Console
● Do not interrupt the user

Fatal Errors
● Displayed in modal dialogs
● Also logged in the Error Console

Users stay productive
Errors remain traceable

Where Is the Error Console Available?

● Lightning Experience
● Salesforce Classic
● Salesforce Mobile App (preview limitation)

How the Error Console Works

● Errors occur on Lightning pages or components
● Non-fatal errors are captured in the background
● Fatal errors appear immediately in modal dialogs
● All errors are stored in the Error Console
● Users can review and share error details later

This creates a non-intrusive yet transparent error-handling experience.

How to Enable Error Console

Step-by-Step Setup

● Go to Setup
● In Quick Find, search for User Interface
● Click User Interface
● Scroll to Advanced Settings
● Enable Use Error Console for error reporting in Lightning Experience
● Save changes

Real-World Use Case

A sales user opens a Lightning record page with a misconfigured component:

● The page loads successfully
● A non-fatal component error occurs
● The user continues working without interruption
● Later, the user opens the Error Console
● Error details are shared with the Salesforce admin

Result:
● No productivity loss
● Faster issue resolution

Conclusion

The Error Console in Salesforce Spring ’26 is a major usability improvement for Lightning Experience. By capturing non-fatal errors quietly and centralizing all error details, Salesforce ensures users stay productive while admins and developers get the insights they need.
