All,
NAME TYPE VALUE ------------------------------------ ----------- ----------------------- large_pool_size big integer 33554432 shared_pool_reserved_size big integer 26843545 shared_pool_size big integer 536870912
as should the target (though the errors says it is coming from the RPC, so this shouldn't be the issue):
NAME TYPE VALUE ------------------------------------ ----------- ----------------------- large_pool_size string 1572792 shared_pool_reserved_size string 2000000 shared_pool_size string 20000000
