Unexpected end of JSON input

Hi all, bought the bot and trying to set it up with Cryptopia exchange, but keeps on coming up with this error in the log:

(node:604) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): Error: Unexpected end of JSON input
(node:604) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

I've re-installed and re-exe the program but still no joy, any ideas of what to do next??
Cheers

I was having this error too using Deviance and a wrong pair name "BTC-USDT", I changed to BTC-IOTA and no more errors

Thanks for the suggestion, but still no luck!!! May be it's Cryptopia that's not playing the right tune.
