4. Check if all the sensitive data in the `masked_response` is masked

```
curl --location '{{base_url}}/analytics/v1/connector_event_logs?type=Payment&payment_id={{payment_id}}' \
--header 'sec-ch-ua: "Not A(Brand";v="99", "Google Chrome";v="121", "Chromium";v="121"' \
--header 'sec-ch-ua-mobile: ?0' \
--header 'authorization: Bearer JWT_token' \
--header 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36' \
--header 'Content-Type: application/json' \
--header 'Referer: https://integ.hyperswitch.io/' \
--header 'api-key: {{api-key}}' \
--header 'sec-ch-ua-platform: "macOS"'
```
Response for Googlepay

```
"masked_response\":\"{\\\"token\\\":\\\"*** alloc::string::String ***\\\"}
```

## Impact Area
> Create payment: Applepay and Googlepay
