endless spinning disc on checkout page with payment gateway filter applied

Hello,

I am using Gravity Forms with Woocommerce. I set the parameters in gravity forms to forward the gravity forms entry id as part of the URL ( e.g. https://www.niester.net/checkout/?entry_id=128 )

I am then using the “woocommerce_available_payment_gateways” filter to apply a transformation to the available gateways based on the data from the specific gravity forms entry id.

Everything works great until I enter the following line of code:

$dif_gf_entry_finaid = $dif_gf_entry['30'];

If I leave that ONE line commented out I don’t get the spinning disc. As soon as I include that line of code I get the spinning disc forever

I’m at a loss and would love any and all help that this community can provide. For reference here is my complete snippet code:

add_filter( 'woocommerce_available_payment_gateways', 'dif_unset_gateway_by_aid' );
  
function dif_unset_gateway_by_aid( $available_gateways ) {
    if ( is_admin() ) return $available_gateways;
    if ( ! is_checkout() ) return $available_gateways;
    
// set unset to true so we remove the check option by default from all types of carts
	$unset = true;

	// get form and entry id of submitted form from query headers
	$dif_gf_entry_id = $_GET['entry_id'];
	$dif_gf_form_id = $_GET['form_id'];

	// retrieve Gravity Forms Entry associated with cart
	$dif_gf_entry = GFAPI::get_entry( $dif_gf_entry_id );
	print_r($dif_gf_entry);
	// retrieve value of financial aid requested "Yes" or "No"
	echo "FIN AID REQ?:  ";
	$fin_aid_key = '30';
	$dif_gf_entry_finaid = $dif_gf_entry['30'];
	
	if ($dif_gf_entry_finaid === "Yes") $unset = false;
	
// check unset credit card variable ($unset) and if true unset cheque.  this is the default status.
    if ( $unset == true ) unset( $available_gateways['cheque'] );
	if ( $unset == false ) unset( $available_gateways['stripe']);
	
    return $available_gateways;
}
