Load layer From Oracle using QgsDataSourceUri in QGIS3 always return Invalid Layer

I’m tring to load spatial layer from Oracle but when i called function QgsVectorLayer(uri.uri(), “LAYER” , ‘oracle’) it still inValid layer

This is my code

> def LoadFromOracle(tablename):
>     GeometryColumn = Get_GeometryColumn(tablename)
>     print("GeoMetry Column is")
>     print(GeometryColumn)
>     oracleSetting = settingdb.GetSettingOracle()
>     uri = QgsDataSourceUri()
>     uri.setConnection(oracleSetting[3], oracleSetting[4], oracleSetting[0], oracleSetting[1], oracleSetting[2])
>     uri.setWkbType(QgsWkbTypes.Polygon)
>     uri.setDataSource('', tablename, GeometryColumn)
>     uri.setKeyColumn('ID1')
>     vlayer = QgsVectorLayer(uri.uri(), tablename, 'oracle')
>     print(uri.uri())
>     print ("uri wkbtype == %s layer geometry type == %s wkbType == %s"%(uri.wkbType(),vlayer.geometryType(),vlayer.wkbType()))
>     crs = QgsCoordinateReferenceSystem("EPSG:24048")
>     vlayer.setCrs(crs)
> 
>     return vlayer

I’m tring to use uri.setWkbType function but it is not working.
When I try to check valid status of QgsVectorLayer with this code.it still “False”

layer = self.LoadFromOracle('PROVINCE')
print ('Layer is valid = %s'%self.layer.isValid())

result of the code :

> dbname='XE' host=127.0.0.1 port=1521 user='SYSTEM' password='SYSTEM' key='ID1' estimatedmetadata=true type=Polygon table="PROVINCE" (GEOMETRY) sql=
> uri wkbtype == 3 layer geometry type == 3 wkbType == 0
> Layer is valid = False 

user = "me"
pWord = "password"

def loadFromOracle(tName, user, pWord):
    uri = QgsDataSourceUri() #Instantiate the uri object

    host = 'bcgw.bcgov'
    port = "1521"
    dbName = 'idwprod1.bcgov'
    uri.setConnection(host, port, dbName, user, pWord)
    
#    uri.setWkbType(QgsWkbTypes.Polygon) # not needed

    schema, table = 'WHSE_LEGAL_ADMIN_BOUNDARIES', 'ABMS_MUNICIPALITIES_SP'
    geom = "SHAPE"
    sql = "admin_area_abbreviation = 'Castlegar'"
    keyColumn = "OBJECTID"
    uri.setDataSource(schema, table, geom, sql, keyColumn)
 
    vLayer = QgsVectorLayer(uri.uri(), tName, 'oracle')
    return vLayer
    
outLayer = "Castlegar"
vLayer = loadFromOracle(outLayer, user, pWord) # FUNCTION CALL
QgsProject.instance().addMapLayer(vLayer)
print(f"Layer {outLayer} added OK!") if vLayer.isValid() else print("Layer failed to load!")
