Not able to use util.find() in openLCA 1.10.3

[swamp-fire]

Hello,
I am trying to run the following on the openLCA python developer tool:

from java.io import File
import sys
import os
from org.openlca.eigen import NativeLibrary
from org.openlca.core.matrix.solvers import DenseSolver
from org.openlca.core.matrix.cache import MatrixCache
from org.openlca.core.math import CalculationSetup, SystemCalculator,
CalculationType
from org.openlca.core.database.derby import DerbyDatabase
from org.openlca.core.database import EntityCache
import org.openlca.core.model as model
from java.util import UUID
from org.openlca.core.model.descriptors import ImpactMethodDescriptor,
CategorizedDescriptor
from org.openlca.io.xls.results.system import ResultExport
import util
from org.openlca.app.db import Cache
from org.openlca.core.matrix import LinkingConfig, ProductSystemBuilder,
ProcessProduct
from org.openlca.core import matrix
folder = '/Users/ayush/openLCA-data-1.4/databases/elcd_3_2_greendelta_v2_18'
db = DerbyDatabase(File(folder))
Cache.create(db)
mass = util.find(db, model.FlowProperty, 'Mass')

However I am getting the following error in my log

`Traceback (most recent call last):

Any idea how to resolve this issue.
Thanks

Hey,
In commit Refactored dao creation in https://github.com/GreenDelta/olca-modules they refractored the creation of daos.
GreenDelta/olca-modules@baa6f7c#diff-09451475fd990189bebff53109fad3a114131437c2b312d36d6481a5830757e9
Just replace Daos.createBaseDao in find.py with Daos.base.
