Django-Graphql mutation works in Playground but Returns null in ReactJS-Apollo

I making a simple update mutation from Graphql Playground, and I believe that if the mutation is working from playground, Hence there is no issue in backend.

mutation{
  emwCustomMessageToCustomerUpdate(
    id:"RU1XQ3VzdG9tSW5mb3JtYXRpb25Gb3JDdXN0b21lcjoxNQ==", 
    input:{
      isActive:false,
      allowClose:false,
      message:"asdfssdf",
      displayLocation:"S1",
      messageHeader:"Dsfsdf"
    }){
    eMWInformationForCheckout{
      message
    }
    errors{
      message
    }
  }
}

Which returns this response indicating call is success, I could verify that.

{
  "data": {
    "emwCustomMessageToCustomerUpdate": {
      "eMWInformationForCheckout": {
        "message": "asdfssdf"
      },
      "errors": []
    }
  }
}

But when I call this mutation from reactjs-apollo, It is not mutating the data, I am mutating a single key, But it makes other keys to null. The mutation i am using from react is :

export const UpdateMessageForCustomer = gql`
  mutation UpdateMessageForCustomer(
    $id: ID!
    $message: String
    $startDate: DateTime
    $endDate: DateTime
    $allowClose: Boolean 
    $displayLocation : String
    $buttonText : String
    $screenPlacement : String
    $messageHeader : String
    $isActive : Boolean
    ){
      emwCustomMessageToCustomerUpdate(id: $id, 
        input:{
        message: $message
        startDate: $startDate,
        endDate: $endDate,
        allowClose: $allowClose,
        displayLocation : $displayLocation
        buttonText : $buttonText
        screenPlacement : $screenPlacement
        messageHeader : $messageHeader
        isActive : $isActive
    }){
      eMWInformationForCheckout{
        message
      }
      errors{
        message
      }
    }
  }
`

function used to mutate in react component

const [UpdateMessageForCustomerMutation] = useMutation(UpdateMessageForCustomer, {
    onCompleted({ emwCustomMessageToCustomerUpdate }) {
        if (emwCustomMessageToCustomerUpdate.errors.length) {
            notify({
                text: intl.formatMessage({
                    defaultMessage: "Message added successfully"
                })
            });
            refetch()
        }
    },
    onError(error) {
        console.log('error', error)

    }
});

and the trigger mutation is as following

const changeMessageStatus = (e, id) => {
    UpdateMessageForCustomerMutation({
        variables: {
            id : id,
            input : {
                [e.target.name]:e.target.value
            }
        }
    })
}
