Facing issue while integrating bot with web/mobile client channel

(Subrahmanyam Donepudi) #22

@dan.stoddart You need not delete the channel though.Incase, if you want the channel to use another application which uses HS256 instead of RS256, you can create another application by selecting the HS256 alg and then associate the new app with the channel.

Below is the difference between RS256 and HS256 algorithms:
RS256 is an asymmetric algorithm, and it uses a public/private key pair: the identity provider has a private (secret) key used to generate the signature, and the consumer of the JWT gets a public key to validate the signature.
HS256 , on the other hand, is a symmetric algorithm, with only one (secret) key that is shared between the two parties

Hi @siripurapurahul,

We hope you have read the responses from the above thread.
Please go through the following solutions to resolve the error, however, this error shouldn’t be blocking the bot functionality.


Kindly implement as mentioned on the above responses and let us know if the issue is still persistent even after making the necessary changes.

Yoga ramya.

I was successfully able to follow the tutorial and connect to the sample Travel Application, but when i try to integrate with my Demo bot i am getting 401 errors.


I have triple checked my Bot_name, bot_id, client_id, and client_secret and gets rid of this error :frowning:


Anyone know where else I should look?

We are using travel planning sample bot for practicing the chatbot implementation with sdkApp.
we chose HS256 algorithm and jwtURL as “http://localhost:3000/api/users/sts”. we are getting following error in node console. browser is displaying “respond with a resource” message.

Failed to lookup view “error” in views directory “D:\dev\SDKApp\sdk”.

Even we tried with “http://demo.kore.net/users/sts” but no luck. This time browser is displaying follwoing message “Cannot GET /users/sts”

Can you please help me in resolving this issue.

Thanks in advance

Hi @yogaramya.mendu @swagata.sengupta Thanks a lot for helping integrating the chat bot in the web /client channel Now i am trying to integrate the chat bot with online REST service as a Action Task .
The API Request Url is : http://dummy.restapiexample.com/api/v1/employee/16332,
Please find the screenshots how i have tried to integrate the Service:
1 2 3

While coming to the Authorization I have given it as none and i didnt define any parameters for the service as they are not required even if everything is fine I am getting this particular error in the output. Please find the screenshot of the error:

Can you guys please help me in that I am really struck with it .

Thanks in advance

I’ve checked the response of this endpoint and see the content-type coming in text/html; charset=UTF-8 format.

Could you please use a Dialog Task instead of the Action task to achieve this requirement?

Please refer to the below snips which could guide you on building a dialog task to achieve the same.

@Subrahmanyam Thanks a lot for the immediate reponse It helped me a lot.

(Rahul Siripurapu) #32

@Subrahmanyam Hi Is there any possibility in Kore.AI that the bot returns a word document based on a Task If possible can you please help me in that through the steps.

Thanks in advance

I have followed all the steps including starting startServer.js and I could load the chat window through http://localhost:3000/UI/ successfully. However I am not able to load it through clicking on index.html. I want to add index.html to another application and execute.
Issue in browser on inspecting is:
Access to XMLHttpRequest at ‘http://localhost:3000/api/users/sts’ from origin ‘null’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource

Please help me resoliving this issue. Thanks!
