“An unexpected error has occurred” after firebase deploy

Question

When I am hosting my web page through firebase hosting then after writing command firebase deploy I got the following error:

Microsoft Windows [Versi         


        

Answer 1

In my case, this error occurred when I had not set the site name in firebase.json.

Example of the firebase.json with site highlighted

Answer 2

In my case, resolve with:

firebase deploy --except functions

Answer 3

It could be due to npm and node version For mac os, you can update npm using command:

npm install -g npm@latest

and update node directly by going to link https://nodejs.org/en/ and download installer. and run

npm install -g firebase-tools

For removing firebase hosting deployment errors (also if you are updating existing hosted site) you can do process again 1] firebase login 2] firebase init 3] firebase deploy

Make sure your current folder has two things: public folder (which contains all files index.html) And firebase.json file

Answer 4

If you still are serving your site on localhost using firebase serve it might cause problems. Shut it down then try the deploy. Worked for me.

Answer 5

Yes I've faced this issue.. This is because of my node version I was using Node v.8.0.0 I just downgrade it to Node v.16.0.3 and then my deployment done :)

Answer 6

Make sure that you are logged in by running firebase login in the terminal.
