Health Check Error: Vardef HTML function custom

Overview

The Health Check wizard must be run when upgrading in order to evaluate your instance's ability to move to the target version. During the health check, various types of issues may be detected which can affect your ability to upgrade. This article will cover the "Vardef HTML function custom" error reported by the health check.

Symptoms

This error generates an output similar to the following in health check: 

Resolution

In this example, the field identified in the health check error is extended in the ./custom/Extension/modules/Accounts/Ext/Vardefs/sugarfield_htmlexample_c.php file. This file contains the following code:

$dictionary['Account']['fields']['htmlexample_c'] = array(
'type' => 'html',
    'function' => array(
        'name' => 'HTML Example',
        'returns' => 'html',
),
);

To resolve this error, the offending code will need to be deleted or commented out since these functions are no longer supported in the target version's framework.

Once the necessary change has been made, please navigate to Admin > Repair and perform a "Quick Repair and Rebuild" to ensure that the changes are synced between the application and database. Then, perform the health check again to confirm that the error is no longer reported.
