After initiating my firebase app with 

firebase init

I tried to deploy it with 

firebase deploy

but I get this error

    === Deploying to 'fugis-auto-services-website'...

i  deploying database, storage, functions, hosting

Error: An unexpected error has occurred.

So I looked at the firebase-debug.log and this is what it says

Tue May 01 2018 19:52:19 GMT-0500 (CDT)

I'm not sure how to proceed.

Too late to answer but might help someone in future, I had the same issue, i added the public folder as mentioned by @Gleb and inside your firebase.json you need to specify the public folder as well, like so:

{
"hosting": {
"public": "public",
"rewrites": [
  {
    "source": "**",
    "function": "helloWorld"
  }
]
}
}

    Thanks for this! It seems the "public" argument is required for hosting to deploy. Note that you also must have an actual folder created, even though it can be empty. – Nick Farina Sep 29 '19 at 18:44

    any ideas why get this error when deploying this: https://github.com/QuantumInformation/svelte-fullstack-starter/blob/master/firebase.json#L11 **The "path" argument must be of type string. Received type undefined at validateString (internal/validators.js:125:11)** – Nikos Dec 31 '19 at 14:23
  • Seems to be true that we need public entry in the hosting object. If thats the case any way to only have cloud function rewrite alone? – Ayyappa Feb 29 '20 at 15:05

I was able to fix this by re-initializing firebase functions: 

firebase init functions

You might want to first update your firebase-tools: 

npm install -g firebase-tools

and backup your existing functions directory.

  • didn't know init can be done separately for functions, firestore etc. `firebase init functions` ran the routine and fixed it for me – Fakeer Jan 28 '20 at 03:44

Had same issue as i use hosting part just to setup headers, public property is necessary! If you not define it you would have this issue

My problem ended up being that I updated my macOS to High Sierra 10.13.4 and that somehow screwed up my paths for nvm. I had to update nvm and I reinstalled Firebase and now things seem to be working.

I was facing the same problem so after debugging for 2 hours I solved the problem by downgrading npm-conf to 1.1.0 with the command npm install npm-conf@1.1.0

I was using a firestore callback like onCreate or onUpdate without passing the actual document path.

functions.firestore
.document()
.onCreate()

Just turn it into

functions.firestore
.document('collection/doc')
.onCreate()
