property value for '__initialmatch__' not getting set

[Kaushalop]

I have been trying to use the json-server example for Rivescript but getting the error:

Cannot set property 'initialmatch' of undefined

Any reasons why this could occur?

What were you doing that caused this bug? If used correctly (e.g. sending a JSON payload to the server) I can't reproduce it normally (even if I forget the "username" or "message" parameters from the payload).

A reliable way I found to reproduce the bug:

1. Start the json server
2. Send a blank JSON object to it, like this:

curl -i \
   -H "Content-Type: application/json" \
   -X POST -d '{}' \                                               
   http://localhost:2001/reply

The server needs the "username" and "message" parameters from the client. If you just go to http://localhost:2001/ in your browser, it gives you a curl command you can copy and paste to test it:

Usage: curl -i \
   -H "Content-Type: application/json" \
   -X POST -d '{"username":"soandso","message":"Hello bot","vars":{"name":"Soandso"}}' \
   http://localhost:2001/reply

I'll update the json-server example to make it a little more 'bulletproof', but bear in mind the example codes are just that, examples; I wouldn't recommend using any of them as-is for production use with many users (for example the json-server does no garbage collection of user variables on its own, so if you threw thousands/millions of distinct usernames at it, it wouldn't scale very well).

It was primarily showing up because the user array was not getting initialised so i fixed the POJO Class that was handling it. Thanks for the help
