Unable to hit sendTransaction api

[Bikram-antech]

Hello @lhartikk
I am newbie and i have downloaded your source code and able to make nodes working and apis mentioned in Naive-chain tutorial.
But now when i moved forward to Naive-coin tutorial, In this project i am able to hit apis from Naive-Chain but apis from Naive-coin is not working. For example: I am hitting send transaction api but it throws me error :

<title>Error</title>

Cannot POST /sendTransaction

Is there something i left or is there something missing in code. Anyone facing same issue? Please reply asap
