The botkit can help accommodate higher payloads. You will need to go to the lib\app\index.js
Update the Application funciton to something like below:

function Application( expressapp , config ){ this.app = expressapp || express(); this.app.use(bodyparser.json({limit: '50mb'})); this.app.use(bodyparser.urlencoded({limit: '50mb', extended: true})); this.config = config; }

Apart from this, you may also need to check if your forward and/or reverse proxy like Nginix has any limitation in the payload.
