Receiving 403 (forbidden) from CLU whenever initiate the bot composer from custom adapter like (wechat, twiliio)

Question

I'm writing a custom adapter of twilio for whatsapp in .net. When I try to send a message from twilio adapter to bot composer it gives me 403(forbidden) from CLU in response of that activity but without adapter it is working fine

I'm new in bot composer.Any direction would be appreciated.

I'm using CLU as recognizer

{
  "$kind": "Microsoft.CluRecognizer",
  "projectName": "${settings.clu.projectName}",
  "endpoint": "${settings.clu.endpoint}",
  "endpointKey": "${settings.clu.endpointKey}",
  "deploymentName": "${settings.clu.deploymentName}"
}

Below is the error:
