Crash when opening contract hash after new contract is uploaded

[lychongaa]

I have set up two nodes node0 and node1 with parity by following their tutorial on Ubuntu 18.04. I have deployed a contract with python web3, and the contract successfully deployed and is displayed in the home of ethereum light.

But when I try to enter the hash page of the contract deployment transaction, etherchain-light crashes with the following error:
npm ERR! Linux 4.18.0-22-generic
npm ERR! argv "/usr/bin/node" "/usr/bin/npm" "start"

npm ERR! npm bugs etherchain-light
npm ERR! Or if that isn't available, you can get their info via:

Why is this happening and how can I fix it? Thanks
