    @Tominaga, Kohei/富永 航平 Are you trying the language service document summarization API?

    Based on the error, it looks like an authentication issue where you have tried to use the Bearer token with the request but the token seems to be invalid. How did you generate the bearer token of your language resource?

    Usually, the bearer token is generated by the issue token API which is used for some scenarios of AI services. In this case, you can actually use the subscription key of your resource in the header to pass the request. You can get the subscription key from the resource page on Azure portal from the Keys + Endpoint blade. Use this key with this header to POST the request.

    -H Ocp-Apim-Subscription-Key: <your-language-resource-key>"

    A sample request is mentioned here for reference.

    curl -X GET https://<your-language-resource-endpoint>/language/analyze-text/jobs/<my-job-id>?api-version=2022-10-01-preview \
    -H "Content-Type: application/json" \
    -H "Ocp-Apim-Subscription-Key: <your-language-resource-key>"\ 
    -d \ 
    <body of request>

    I hope this helps!!

    HI Tominaga

    Seems like you are having error with the api endpoints, Ensure that the API key you're using in the "Authorization" header is correct and hasn't expired this might be the problem. You can obtain the API key from the Azure portal by going to your Text Analytics resource and looking for the "Keys and Endpoint" section. in that section you will find 2 keys use any one of them and hopefully it works this time.

    If this helps kindly upvote and accept the answer for assistance ping here thanks much.
