PhpMyAdmin\SqlParser\Exceptions\LoaderException: (2 replies)

Windows10-64bit,
version-3.0.6,
apache-2.4.27,
php-7.1.9,
mysql-5.7.19,
icon-orange,
127.0.0.1 localhost
::1 localhost,
localhost-yes,

c:/wamp64

The icon was green, but for some reason, stays orange, localhost and phpmyadmin working ok.

I'm trying to debug a php website in visual studio code.

I installed XDebug extension.
I started the debugger, then submitted a form.
The debugger opened Context.php located at
C:\wamp64\apps\phpmyadmin4.7.4\vendor\phpmyadmin\sql-parser\src
and as I stepped over the code, I got the following exception

PhpMyAdmin\SqlParser\Exceptions\LoaderException: Specified context ("\PhpMyAdmin\SqlParser\Contexts\ContextMySql50710") does not exist.

Contexts folder is under src, not SqlParser as stated in the exception.
C:\wamp64\apps\phpmyadmin4.7.4\vendor\phpmyadmin\sql-parser\src\Contexts contains
ContextMySql50000.php,ContextMySql50100.php,ContextMySql50500.php,ContextMySql50600.php,ContextMySql50700.php

What does this mean?
