The specified resource does not exist

[lijualivenow]

I am running sample code locally by clicking index.html , I am getting the following error

{
    "message": "BadRequestException: INVALID_REQUEST - Invalid bot name or alias."
}

Anyone how to run the sample code, or any proper tutorial

I am also stuck, getting this and other errors if used a bot name or alias

{
    "message": "The specified resource 'botName' does not exist. Choose another resource."
}
