Error when i'm trying to deploy nextjs on cloud functions

[jackmatrix]

I am trying to make nextjs works together with firebase cloud functions.

When i am testing locally, there is no problem my app works perfectly.

However when i am deploying there is an error related to this line

const app = next({ dev : false })

When i put this line, my functions cannot be deployed and i get this message

Deploy Error: Function load error: Error: cannot communicate with function.

I don't understand because i don't have this issue in local testing.

Then when i comment this line. It's okay i can deploy my functions. However there is no possibility to use next.js . So this is the problem.

I have this error even without using any nextjs stuff in my functions. Just the fact to declare the line

const app = next({ dev : false }) prevent my app to deploy

any suggestions ?
