As per the error message it looks like Microsoft Language Understanding Authoring Account and Microsoft Language Understanding Prediction Account have not been provisioned. Are there any changes with these Resources and may I know when these resources are created. Because as we know
Language Understanding (LUIS) will be retired on 1 October 2025. Beginning 1 April 2023, you won't be able to create new LUIS resources. A newer version of language understanding is now available as part of Azure Cognitive Service for Language.
Conversational language understanding (CLU), a feature of Azure Cognitive Service for Language, is the updated version of LUIS.
Please share more information with us along with the documentation you have followed.
