Getting exception when starting Rocket Chat: Cannot find module './isBlank'

[distlibs]

Description:

I git pull latest changes from develop branch and when I start Rocket Chat server using meteor command I get exception:

Exception in callback of async function: Error: Cannot find module './isBlank'

I think its related to LiveChat. Because I get error when compiling LiveChat:

pm ERR! Cannot read property '0' of undefined
