-## Handle Extensions API errors when the dashboard is not visible
 
- In Tableau Server or Tableau Online version 2018.3 and later, when the browser window is not visible (that is, when the browser window Tableau is running in is minimized or in the background), the Extensions API method calls are blocked and an error object is returned. If you have code that might run when the dashboard is not visible, you should add code to check if the window is visible so that you can handle the error. If you are using `tableau-extensions-1.1.0.js` or later, the error code returned in this case is `VISIBILITY_ERROR`.
-
-### What happens when the error occurs
-
- This error can occur if an Extensions API method is called while Tableau is not in the foreground. For example, this could happen if the user switches tabs or minimizes the browser window and there is a timer that triggers the API call. When the user subsequently returns to the dashboard view, an error dialog box will appear.

-
-
-### Identifying the error as a visibility-error
-
- To find out the cause, you can use the debugging tools in the browser. If you check the Console window, in Chrome for example, you might see an error message similar to the following.
-
-   ![]({{site.baseurl}}/assets/ext_visibility_err_console.png)
-
-
-### Add a check for visibility and add an event listener
-
-The Extensions API methods are intended to be used in scenarios where some manual interaction is required. However, there might be cases where a method is called on an interval, or there is a delay in execution, and the browser window that contains the extension is no longer visible when the method call is made. In these cases, you could use the [Page Visibility API](https://developer.mozilla.org/en-US/docs/Web/API/Page_Visibility_API) and an event handler to avoid having your users encounter the `visibility-error`.
-
-
-The following example shows how this error could be handled using an event listener for `visibilitychange`. You can create your own `visibilityhandlermethod` method if you need to wrap your Extensions API calls when the browser window is visible.
-
-
-```javascript
-
-
-    document.addEventListener('visibilitychange', visibilityhandlermethod, false);
-
-
-    // 
-    function visibilityhandlermethod() {
-     if (document.hidden) {
-         // do something while you pause the extension execution
-      }    else  {
-            // do stuff
-        // call the Extensions API
-      }
-    }

-* The Extensions API library version 1.2 (`tableau-extensions-1.2.0.js`) is backward compatible with previous releases of the library. You can use the Extensions API library version 1.2 for extensions on Tableau 2018.2 and later. The library contains logic to handle any necessary conversions for the supported version of Tableau the extension is running in. For the best experience, you should always use the latest version of the library with the extensions you create.

+* The names of the Extension API library files have changed. The hypens (-) have been removed from the file name (was `tableau-extensions-*`, now `tableau.extensions.*`). Starting with the 1.2 library, the names of the library files are as follows: 
+```

+tableau.extensions.1.2.0.min.js
+tableau.extensions.1.latest.js

+**Note** If you have previously been referencing `tableau-extensions-1.latest.js` in your code, you will need to use the new naming convention when you upgrade to the 1.2 library (`tableau.extensions.1.latest.js`).

A dashboard extension is a web application that runs inside the Tableau dashboard, and as a web application, your dashboard extension could be vulnerable to cross-site scripting (XSS). Cross-site scripting is an attack where a malicious user injects client-side code (typically, JavaScript) to execute in your web application.
