--------------------------+-----------------------------
 There is one condition added that is preventing correct behaviour of REST
 Expected behaviour:
 when API call result is null for GET methods (where nothing is found
 e.g.), should be encoded as null in JSON.

 Actual  behaviour:
 when API call result is null, empty string is returned producting EOF
 Error on receiving end.


 in file wp-includes/rest-api/class-wp-rest-server.php line 404:

 {{{#!php
 <?php
 // The 204 response shouldn't have a body.
 if ( 204 === $code || null === $result ) {
   return null;
 }

 }}}
 should be fixed with:

 {{{#!php
 <?php
 // The 204 response shouldn't have a body.
 if ( 204 === $code ) {
   return null;
 }
 }}}
