Why is my build completing fine but deployment takes forever?

I can build and deploy fine with an extremely barebones index.js but when I put this one in:

It just takes forever to deploy. It builds in 4m17s and everything after is extremely slow.

Hi @iDominusU

We can only see one site on your account with one deploy and it appears to have deployed in about 3 seconds. We must not be looking in the right place. Could you send a link to the deploy log for the problematic build?

That seems to be an invalid link.
