Change Text Strings On Specific WooCommerce Endpoints - php

Question

I'm trying to conditionally change strings on WooCommerce My Account Endpoints. Each time I try to add an endpoint condition it either breaks the site or doesn't work; however when I don't use the condition the string replace works. Maybe someone can point out where I'm going wrong.
Working Snippet - Without Condition
function change_endpoint_text( $translated ) {
$translated = str_ireplace( 'List of coupons which are valid & available for use. Click on the coupon to use it. The coupon discount will be visible only when at least one product is present in the cart.', 'List of vouchers which are valid & available for use. Click on a voucher to use it. The discount will be visible only when at least one product is present in the cart.', $translated );
return $translated;
}
add_filter( 'gettext', 'change_endpoint_text' );
Conditional Snippet Test - Not Working
Note: I also tried using an is_account_page condition that seemed to break the site.
function change_endpoint_text( $translated ) {
if( is_wc_endpoint_url('wc-smart-coupons') ) {
$translated = str_ireplace( 'List of coupons which are valid & available for use. Click on the coupon to use it. The coupon discount will be visible only when at least one product is present in the cart.', 'List of vouchers which are valid & available for use. Click on a voucher to use it. The discount will be visible only when at least one product is present in the cart.', $translated );
}
return $translated;
}
add_filter( 'gettext', 'change_endpoint_text' );
Any help would be appreciated.

You can also check for end points using $wp->query_vars['custom_endpoint'].
For example,
function change_endpoint_text ( $translated_text, $text, $domain ) {
global $wp;
if ( isset( $wp->query_vars['wc-smart-coupons'] ) ) {
if ($translated_text == 'some existing text') {
$translated_text = __( 'The new replaced text', 'woocommerce');
}
}
return $translated_text;
}
add_filter( 'gettext', 'change_endpoint_text' );
