Note the lambda function name created by serverless. You need to tell your Lex Bot to use this lambda as done in below screen shot.
Please note that my Lex Bot has 4 intents and all are full filled by same lambda function.
- HelloIntent - Notify Raspberry Pi to capture image and then use AWS Recognition to recognize face.
- NameIntent - When face is not matched with already indexed faces, index the new face
- CloseIntent - Simply ternimates conversation
- ClearAllFacesIntent - Remove all indexed faces from collection
Inside handler.js file, you will find
process.env.URL_CAPTUREYou need to add this as environment varialble in your lambda console and value should be end point of your Image server (https://github.com/just4give/raspi-image-server) running on your pi. For example if your pi's external IP is x.x.x.x and Image server is running on port 80, then URL_CAPTURE should be http://x.x.x.x:80/api/capture as below
