Comment:

 Hi @simongcc. It seems like there's a problem with the priority of the
 filter you're adding:

 {{{#!php
 <?php
 add_action( 'wp_print_footer_scripts', 'set_member_meta', 20 );
 }}}

 This filter has a priority `20`.
 [https://core.trac.wordpress.org/browser/tags/6.8.2/src/wp-includes
 /default-filters.php#L364.
 [https://core.trac.wordpress.org/browser/tags/6.8.2/src/wp-includes
 /default-filters.php#L364 The scripts are actually printed as part of this
 action] with the default priority of `10`:

 {{{#!php
 <?php
 add_action( 'wp_print_footer_scripts', '_wp_footer_scripts' );
 // https://core.trac.wordpress.org/browser/tags/6.8.2/src/wp-includes
 /script-loader.php#L2266
 function _wp_footer_scripts() {
   print_late_styles();
   print_footer_scripts();
 }
 }}}

 The data is being attached to the script _after_ the script was printed,
 because the `20` priority action will run later. The following should fix
 your example by using a lower priority:

 {{{#!php
 <?php
 add_action( 'wp_print_footer_scripts', 'set_member_meta', 5 ); // Use 5
 instead of 20.
 }}}

 Hope that helps!
