Missing token or secret

Hi, I’m not sure whether this is a directline issue or webchat but i’m getting the following error

{
  "error": {
    "code": "BadArgument",
    "message": "Missing token or secret"
  }
}

even after i’m providing the correct secret (that i’ve verified from azure)

I’m using master/webchat-es5.js (dated 24-Apr-2019)

To give more context to how i’m using is I’m running the bot in my local using ngrok and setting the url to bot channel registration i did on azure using the secret from the bot channel registration i’m building the webchat

in ngrok i’m getting following error (OPTIONS /api/messages 405 Method Not Allowed)

Here is the screenshot of all the action.type i’m getting back from webchat

But after some time (if I leave it for 10mins ) it starts working, it is happening every time

The caching is not new. If you were creating new bots then they would be read immediately because they’re not in the cache. But existing bot records have been cached for as long as I know.

It looks like you are correct. You have to change the bots messaging endpoint while the bot is not running otherwise it will not update correctly. Thank you for your help in diagnosing this issue.
