Abfangbarer schwerwiegender Fehler: Objekt der Klasse __PHP_Incomplete_Class konnte nicht in Zeichenfolge konvertiert werden

Question

Ich habe einen Fehler, wenn ich eine einfache Seite öffnen möchte. Dies ist der vollständige Fehler:

ContextErrorException: Catchable Fatal Error: Object of class __PHP_Incomplete_Class could not be converted to string in /Applications/mampstack-5.4.20-0/apache2/htdocs/engelsvandenbroecke/vendor/symfony/symfony/src/Symfony/Component/Security/Core/Authentication/Token/AbstractToken.php line 70

Was ich in meinem Symfony-Projekt getan haben, ist:

• generieren Einheiten aus der Datenbank
• Benutzer bearbeiten Entity für Sicherheit
• bearbeiten security.yml
• Hinzugefügt zwei datefixtures

Das ist mein User-Entity-Klasse:

Answer 1

in der Regel Dieser Fehler bedeutet, dass Sie versuchen, für das Objekt ohne geladenes Klassenobjekt deserialze. Also sollten Sie diese Klasse irgendwie definieren (z. B. eine Datei mit einschließen) und sie dann deserialisieren.

Answer 2

Für mich half das Löschen von Cache/Cookies im Browser. (In der Browser-Sitzung wurde die alte Version der Entität des Benutzers gespeichert).
