Cannot POST the SAS url from my blob storage in creating a new azure speech services' batch transcription

Hi all, 

 

i am trying to create a flow that is triggered as soon as a file is uploaded into my blob storage. 

The trigger is "When a blob is added or modified", and the goal is to give an url to the speech to text api: <Microsoft> developer portal

Below is the flow

It returns the following error:

{
    "statusCode": 400,
    "headers": {
        "Transfer-Encoding": "chunked",
        "api-supported-versions": "2.0,3.0",
        "api-deprecated-versions": "2.0",
        "apim-request-id": "XXXXXXXXXXXXX",
        "x-content-type-options": "nosniff",
        "Strict-Transport-Security": "max-age=31536000; includeSubDomains; preload",
        "Date": "Sun, 28 Mar 2021 21:11:48 GMT",
        "Content-Type": "application/json; charset=utf-8",
        "Content-Length": "631"
    },
    "body": {
        "errors": {
            "contentUrls": [
            ]
        },
        "title": "One or more validation errors occurred.",
        "status": 400,
        "extensions": {
            "traceId": "|"
        }
    }
}
 
It must be noted that if I use "contentContainerUrl": "<SAS URL to the Azure blob container to transcribe>" instead of "contentUrls":  "<URL to an audio file 1 to transcribe>", it works.
 
Thank you in advance and best regards,
 
Vittorio
