[xdebug-general] PhpMyAdmin\SqlParser\Exceptions\LoaderException

I'm trying to debug php in Visual Studio Code. I've started the XDebug.
VSC opens

C:\wamp64\apps\phpmyadmin4.7.9\vendor\phpmyadmin\sql-parser\src\Context.php

and throws this exception

Exception has occurred:

PhpMyAdmin\SqlParser\Exceptions\LoaderException: Specified context

("\PhpMyAdmin\SqlParser\Contexts\ContextMySql50719") does not exist.

The following files exists at

phpMyAdmin/vendor/phpmyadmin/sql-parser/src/Contexts/

ContextMySql50000.php,ContextMySql50100.php,ContextMySql50500.php,ContextMySql50600.php,ContextMySql50700.php,

ContextMySql80000.php

Can anyone explain what this is/means?
