Speech Service Authentication Issue on Bot Framework V4

81 Views Asked by Amintas Lopes Neto At 17 April 2025 at 09:15

Getting the following error while trying to get a token from Azure Speech Service. 'https://brazilsouth.api.cognitive.microsoft.com/sts/v1.0/issuetoken 401 (Access Denied)'.
Here is the way I'm requesting the token via JavaScript:
const res = await fetch('https://brazilsouth.api.cognitive.microsoft.com/sts/v1.0/issuetoken', { method: 'POST', headers: { Authorization: 'Bearer ' + 'MY_SPEECH_SERVICES_SUBSCRIPTION_KEY'}}); const { authorizationToken } = await res.json(); webSpeechPonyfillFactory = await window.WebChat.createCognitiveServicesSpeechServicesPonyfillFactory({ authorizationToken, region });
My bot works fine if I get a token manually via Windows PowerShell though.
What could be possibly wrong? Thx in advance
