I have an issue with creating a Wise transfer to the recipient using this API doc:

Creating a recipient and quote was successful. However, when I create a transfer POST request to /v1/transfers, I have this response:

{
 "errors": [
  {
   "code": "not.found",
   "message": "Not Found",
   "arguments": []
  }
 ]
}

The request was like this:

{
 "sourceAccount": ...,
 "targetAccount": ...,
 "quoteUuid": "...-...-...-...-...",
 "customerTransactionId": "...-...-...-...-...",
 "details": {
  "reference": "to my friend",
  "transferPurpose": "verification.transfers.purpose.pay.bills",
  "transferPurposeSubTransferPurpose": 
  "verification.sub.transfers.purpose.pay.interpretation.service",
  "sourceOfFunds": "verification.source.of.funds.other"
 }
}

All IDs are correct and customerTransactionId was generated randomly.

What may be the reason for this error "Not Found"?

Thank you
