Get one Item rest api is not working with multiple query parameters

Hello All,

I am trying test a get one item rest api with multiple query parameters

/fscmRestApi/resources/11.13.18.05/itemsV2/{itemsV2UniqID}

The query parameters is as mentioned below As I need item number only for CIM organization code

/fscmRestApi/resources/11.13.18.05/itemsV2?q=ItemNumber='123'%26OrganizationCode='CIM'

It gives 200 ok but doesn't give the response payload.
