问题
I am trying to set up my LUIS app in luis.ai (because it seems like I can't set it up in Azure directly?). Anyway, I have created a Language Understanding Intelligent Service (LUIS) (preview) resource, but when I enter one of the keys from that resource into "My Keys" in luis.ai, I get this error: "Bad Argument, Invalid Subscription Key"
Also, I just tried to publish an app with the bootstrap key and got the following errors:
{ "statusCode": 401, "message": "Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription." }
回答1:
As provided in comments, the solution is to use a correct end-point. This is not clear anywhere, but for the luis.ai portal, I have to use WestUS endpoint.
If I change to useing eu.luis.ai, I have to use the WestEU end-point.
回答2:
To use european LUIS endpoint within Bot Builder C# SDK, just modify Luis Model parameters as follows:
[LuisModel("YOUR-LUIS-APP-ID", "YOUR-LUIS-EUROPEAN-KEY", domain: "westeurope.api.cognitive.microsoft.com")]
Note that you'll need to export your LUIS app over EU.LUIS in order to access the correct endpoint.
Hope it helps.
