}Response 400
This error can be returned if the request's parameters are incorrect meaning the required parameters are missing, malformed, or too large.
Response 401
You do not have access.
Reasons can include:
- invalid, malformed, or empty subscription key
- subscription key doesn't match region
Response 403
You're not allowed to complete the request.
Possible reasons:
- Total monthly key quota limit exceeded. If you created a LUIS key to increase your quota, make sure to change the subscription key used in the endpoint request.
- You don't have the permission to access the application.
Response 404
The requested application doesn't exist or isn't published in this region.
Response 409
The application is being loaded, please retry the request.
Response 410
Your application is not supported by this API. Re-train and re-publish your application.
Response 414
The query is too large. Reduce your query to the maximum characters.
Response 429
Too many requests. If you created a LUIS key to increase your quota, make sure to change the subscription key used in the endpoint request.
