Hallo zusammen, kennt jemand diesen Fehler und auch die Abhilfe: [quote] Ups! Ein Fehler ist aufgetreten! Die nachfolgenden Hinweise sollten Ihnen weiterhelfen. Unknown column type “” requested. Any Doctrine type that you use has to be registered with \Doctrine\DBAL\Types\Type::addType(). You can get a list of all the known types with \Doctrine\DBAL\Types\Type::getTypesMap(). If this error occurs during database introspection then you might have forgot to register all database types for a Doctrine Type. Use AbstractPlatform#registerDoctrineTypeMapping() or have your custom types implement Type#getMappedDatabaseTypes(). If the type name is empty you might have a problem with the cache or forgot some mapping information. in vendor/doctrine/dbal/lib/Doctrine/DBAL/DBALException.php on line 183 Stack trace: #0

installiert. Den haben wir dann installiert und der FEhler war weg. Kennt jemand die Ursache? Danke und viele Grüße, Alex
