Trailing comma error “$gradient_attr_key” should not have trailing comma:
Correct function in the file:
function get_background_color_var(
$attributes,
$bg_color_attr_key,
$gradient_attr_key
) {
if (!empty($attributes[$bg_color_attr_key])) {
return $attributes[$bg_color_attr_key];
} else if (!empty($attributes[$gradient_attr_key])) {
return $attributes[$gradient_attr_key];
} else {
return "";
}
