Having error "options.uri is a required argument" when checking out from cart

[WaiLoonTan]

Hi,

I managed to get everything run, all functions is fine.

But when i clicked "Proceed to Checkout" from cart, it shows this error in the browser console

error: {"message":"options.uri is a required argument","error":{}} referencing client.js line 108.

When i ssh to the front-end container and check NPM and Node version,

NPM : v6.9.0
Node : v10.16.0

Thanks in advance
