PHPDox is installed via composer and xdebug is installed in version 2.9.8

Does someone know how to fix this issue?

I'll try to have a look tomorrow when travelling.

Hello, the problem was in a PHPUnit Test class. I don't know why this error is occuring but i removed the class and everything worked.

Here is the class and the problem occurs in the function testDatabaseUtilsGetInstalledMigrationVersion2

<?php

namespace Library\Tests;

use Codeception\PHPUnit\TestCase;

        $this->assertEquals("Test", Converter::firstLetterUp("test"));
        $this->assertEquals("Test", Converter::firstLetterUp("TEST"));
        $this->assertEquals("Test3", Converter::firstLetterUp("TesT3"));

        $this->assertEquals(61445, Converter::hexStringToInteger("F005"));

    }

        $generated2 = Generator::uniqueString(32);
        $this->assertFalse($generated === $generated2);
        $this->assertEquals(4, strlen($generated));
        $this->assertEquals(32, strlen($generated2));
    }
