BDD and when trying the following the parameters in the feature file are not getting picked up. Am I missing a setting python side or a formatting issue with the feature file.

import pytest ,logging
from pytest_bdd import given, when, then, scenarios, parsers

LOG = logging.getLogger(__name__)
ROW_MAX_LENGTH = 100

parametersused =""

scenarios("../features/Duplicate_check.feature")

@given(parsers.parse("{parameters}"))
def ParseParmeters(parameters):
    global LOG
    LOG.debug("Parameters: " + parameters)
    #used to called given
    global parametersused
    parametersused = parameters

Feature file:

Feature:Check if data of given attributes is NOT NULL
    Scenario: Duplicate_check

        Given <parameters>
        When SQL to execute:
            SELECT  
            '%TST_CD' AS Test
            ,(SELECT  PROC_DATE FROM V_UTIL.PROCESSING_DATES  WHERE PROC_DATE_TYP_CD = '%Proc_Typ_Cd') AS Business_Date
            ,'%Data_Entity' AS Data_Entity
            ,'%Data_Attribute' AS Data_Attribute
            ,'FAIL' AS Test_Sql_Status
            FROM 
            (    
            SELECT CASE WHEN COUNT(1) = 0 THEN 'PASS' ELSE 'FAIL' END AS RESULT
            FROM ( SELECT LMT_ID,LMT_TYP_CD
            FROM {$ENV}.LI
            WHERE PROCESS_NAME='proc'  
            GROUP BY 1,2
            HAVING COUNT(1) > 1)A
            )  tst_SQL
            WHERE tst_SQL.RESULT= 'FAIL';
        Then EXPECTED_RESULT=NO_ROWS_RETURNED

        Examples:
        |parameters|  
        |TST_CD=Duplicate_check; Data_Entity=ENT ;PROCESS_NAME=PROC001; Data_Attribute=DA,AD;Proc_Typ_Cd=PROC|
