Comment:

 Ok, I was able to prevent the PHP notice by changing the code to the
 following:

 {{{#!php
 register_meta(
         'post',
         'swisscomkbw-authors',
         [
                 'type'         => 'array',
                 'single'       => true,
                 'show_in_rest' => [
                         'schema' => [
                                 'type'  => 'array',
                                 'items' => [
                                         'type' => 'string',
                                 ],
                         ],
                 ],
         ]
 );
 }}}


 This means the documentation for `show_in_rest` in `register_meta()` needs
 to be updated too to mention that both booleans and arrays are supported.
