Hi community,
I tried to update my Nextcloud 20 to Nextcloud 21 (doesnāt matter if 21.0.0 or 21.0.1). I always get this error. I suspect, it has something todo with my mysql table, but I cannot find out whats the problem. I also tried googling this error but found nothing, so I am posting here.
I am running ngxinx and mysql8. The php version doesnāt matter. I have tried 7.3, 7.4 and 8.0.
OC\DB\Exceptions\DbalException: Unknown column type "json_array" 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 forgotten 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.
Do you have any Idea what could be wrong?
Thanks a lot in advance
Chris
