Speech2Text API does not accept an Object in customeProperties field anymore

Requests to transcribe failed with BadRequest from 15.01.2025.
Microsoft updated API in silent mode

The problem is - when we are sending request to transcribe in payload we send this field

"customProperties": {
"retryCount": 0,
"DevEnvName": "local",
"Provider":"Cloud9Client"
}

customeProperties was key value pair they changed to
and now we have BadRequest with the next error
{
"code": "InvalidPayload",
"message": "$.customProperties.retryCount: The supplied value is invalid."
}

Search the Speech2Text API specifications for the customProperties schema and inspect how its values are currently represented. Compare that schema with the reported InvalidPayload response and the updated Microsoft API behavior; done means the relevant specification matches the current request contract.
