Embedded Service Chat Widget Offline in Digital Experiences Due to Content Security Policy (CSP) Error

Fecha de publicación: May 14, 2026
Descripción

When accessing a Digital Experiences (Community) site, the Embedded Service Chat widget may not go online even when agents are available and in an online status. This occurs due to a Content Security Policy (CSP) configuration issue in the Community Builder.
A Content Security Policy (CSP) is a browser security feature that restricts which external resources a web page can load. When the CSP setting in Community Builder does not include the required Salesforce Live Agent endpoint with a trailing slash, the embedded chat widget fails to initialize.
The following error appears when viewing the community via the Builder option in Setup:
"Access to [Live Agent endpoint URL] for script resources violates your Content Security Policy (CSP). To get access to those script resources, change your Security Level on the Security page in your community's settings."
The exact URL in the error varies depending on the org's Live Agent endpoint and identifying information specific to the org.

Solución

To resolve this error, update the Content Security Policy (CSP) setting in your Digital Experiences (Community) Builder by adding a trailing slash to the Live Agent URL entry.

How to Fix the CSP Error in Community Builder

Navigate to the CSP settings using the following path:
Setup > Digital Experiences > All Sites > Select "Builder" on the affected community > Settings (top left corner of the community builder) > Security
In the Content Security Policy (CSP) section, locate the Live Agent URL entry that corresponds to the error in the Description section.
Add a trailing slash (/) to the end of the URL entry.
Example:
Before: `<REDACTED>
After: `
Save the changes. The chat widget should now initialize correctly when agents are online.
Note: The specific Live Agent endpoint URL varies depending on the affected org. Refer to the error message in the Description section to identify the correct URL to update.
