Displaying PHP Errors from admin-ajax.php

WordPress by default hide errors for ajax request call. This can be confirmed from the source file wp-includes/load.php#L352, here:

if ( defined( 'XMLRPC_REQUEST' ) || defined( 'REST_REQUEST' ) || ( defined( 'WP_INSTALLING' ) && WP_INSTALLING ) || wp_doing_ajax() ) {
    @ini_set( 'display_errors', 0 );
}

See the function wp_doing_ajax() is being used in the conditional statement thus the display_errors is being set.

To workaround this, you need to turn on error reporting manually at top of your ajax function call as suggested by @Friss.
