get_current_wp_release() returns null, if the API responds with an error:

wordpress-beta-tester/src/WPBT/WP_Beta_Tester.php

Lines 240 to 242 in d6510bf

    
           if ( is_wp_error( $response ) ) { 
        
           	return null; 
        
           }

This value is used as 2. parameter in explode():

$current_release        = $this->wp_beta_tester->get_current_wp_release();
$next_release           = array_map( 'intval', explode( '.', $current_release ) );

With PHP 8.1 I get an error:
Deprecated: explode(): Passing null to parameter #2 ($string) of type string is deprecated

Thanks for the debugging. I'll get this updated and released.

Fixed. b28a5fb
