I followed the upgrade instructions from neos.io. But using the ./flow command to check if all deps are OK throws this exception for a 3rd party package:
The object "array" which was specified as a property in the object configuration of object "Vendor\NodeCrudProcessor\ProcessorRegistry" (automatically registered class) does not exist.
Check for spelling mistakes and if that dependency is correctly
This error occurs for every attempt to inject a dependcy like:
* @var array
* @var \Neos\Utils\Arrays
do you have any ideas what went wrong?
