Abha Validation using Mobile OTP issue

When we are calling the initAPI(https://dev.abdm.gov.in/gateway/v0.5/users/auth/init), getting following response on webhook

{
“requestId”: “93b06a99-73da-4d62-b9ae-d21c0b61321a”,
“timestamp”: “2023-06-07T07:11:44.082405801”,
“auth”: null,
“error”: {
“code”: 1511,
“message”: “Cannot process the request at the moment, please try later.”
},
“resp”: {
“requestId”: “67d5f63b-426d-4806-9f9b-c2c753d11f41”
}
}

At the time of calling the initAPI, body was as
{
“requestId”: “67d5f63b-426d-4806-9f9b-c2c753d11f41”,
“timestamp”: “2023-06-07T07:11:38.424Z”,
“query”: {
“id”: “sarkumpan@sbx”,
“purpose”: “KYC”,
“authMode”: “MOBILE_OTP”,
“requester”: {
“type”: “HIP”,
“id”: “dm-demo-HIP01”
}
}
}

OTP was delivered to mobile but in response got 1511 error(Cannot process the request at the moment, please try later.)
