1. fix your flow - see [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)
2. what platform - i.e.os and release
3. what version of NR and node.js
4. what 'contrib' nodes are you using? i.e. node-red-contrib-xxxxxxxx

@Umang please re-export your flow and share it again. The original one you shared is not valid json, and I guess you copy and pasted it when reposting it - so it's still invalid.

A quick scan through your flow json I can see it is only use default nodes, so don't worry about the `contrib` question.

Thanks for sharing your flow.  
Yes, I see this is the Coursera assignment you've shared. Please remember the honour code you signed on joining the course regarding sharing solutions online.

You don't say where you hit that error, so I'm not sure how we can help.
