I am trying to use a QnA Maker knowledgebase with a bot. The official instruction says to open settings with advanced (JSON) view to add the knowledgebaseid, endpointkey, and hostname. However, when I try to do that, it keeps showing "Loading." So, I added the necessary parameters in the settings/appsettings.json file. It works temporarily, but if I close the Composer, it erases the endpointkey parameter. So, everytime I close the composer, I need to add the endpointkey manually. When I published the bot to Azure, I am getting an error
The format of value ‘EndpointKey System.Collections.Generic.Dictionary`2[System.String,System.Object]’ is invalid.
I used the App Service Editor to look at the appsettings.json file, and it shows
"endpointKey": { "message": "Waiting for QnA Maker" },
How can I make the endpointkey permanent? Also, if I edit the file in App Service Preview, how can I build the bot from there?
