Virtal Assistant throwing 'Sorry it looks like something went wrong' - azure

Question

I have created a virtual assistant using the Microsoft virtual assistant template. When testing in the emulator whatever message i send i am getting a 'something went wrong reply.'
I am new to the entire bot framework ecosystem and it is becoming very difficult to proceed.
In the log what i can see is:
[11:26:32]Emulator listening on http://localhost:65233
[11:26:32]ngrok not configured (only needed when connecting to remotely hosted bots)
[11:26:32]Connecting to bots hosted remotely

[11:27:48]POST200directline.postActivity
From what I understood the 'en' is not present in dictionary and I am not sure what is means. I checked in the Responses folder and could not see an en file not sure if that is the issue:
My emulator screenshot is attached:
Any help would be useful.

Answer 1

I believe the issue you are experiencing is a problem on the following lines inside MainDialog.cs:
var locale = CultureInfo.CurrentUICulture.TwoLetterISOLanguageName;
var cognitiveModels = _services.CognitiveModelSets[locale];
This tries to use the locale (retrieved from the current thread as per this documentation) as the key to access the cognitive models in your cognitivemodels.json file.
Inside your cognitivemodels.json file it should look like:
{
"cognitiveModels": {
// This line below here is what could be missing/incorrect in yours
"en": {
"dispatchModel": {
"type": "dispatch",
"region": "westus",
...
},
"knowledgebases": [
{
"id": "chitchat",
"name": "chitchat",
...
},
{
"id": "faq",
"name": "faq",
...
},
],
"languageModels": [
{
"id": "general",
"name": "msag-test-va-boten_general",
"region": "westus",
...
}
]
}
},
"defaultLocale": "en-us"
}
The en key insides the cognitiveModels object is what the code is trying to use to retrieve your cognitive models, thus if the locale pulled out in the code doesn't match the locale keys in your cognitivemodels.json then you will get the dictionary key error.
EDIT
The issue the OP has was a failed deploy. The steps we took were to:
Checked the deploy_log.txt inside the Deployment folder for errors.
If this case it was empty - not a good sign.
Checked the deploy_cognitive_models_log.txt inside the Deployment folder for errors.
There was an error present Error: Cannot find module 'C:\Users\dip_chatterjee\AppData\Roaming\npm\node_modules\botdispatch\bin\dispatch.js.
To fix this error we reinstalled all of the required npm packages as per step 5 of this guide then ran the deploy script as per this guide.
