Error: An unexpected error has occurred.

Note

I had to explicitly uninstall my global firebase install prior to it updating from 4.0.2 (in previous bug report) to 7.11.0. But as you can see it is on the new version now.

This issue does not seem to follow the issue template. Make sure you provide all the required information.

[SeanDez]

What field is missing?

[bkendall]

In your firebase.json file, do you have a value set for functions, or functions.source? If you do, that may be causing this issue. (The docs regarding that setting)

[bkendall]

(don't worry about the bot's message - the missing section is "Test Case", though)

[SeanDez]

I do not but I theorized that I may need to run firebase init again in case it would add new settings. It did not add a source property but the emulators have successfully loaded as a result anyways.

During the new init

• I overwrote files I did not touch, mainly config files.
• I did not overwrite my typescript or server related files (I'd been working in /functions)

[doublejosh]

@SeanDez Confirmed. After cloning a working firebase repo and running npm install I wasn't able to run firebase deploy ...couldn't get to the step ensuring "all necessary APIs are enabled."\

After running firebase init everything works fine.

[tstirrat]

This also fails if you have functions emulator port specified and there is no functions directory structure: #2112

[albertvp]

Same issue of validateString with the same TypeError but doing any deploy firebase deploy --only hosting. Even logging out and in, creating a new project and reinitializing the whole firebase config files. Using Firestore & Hosting only.
firebase@7.14.1
node@14
Worked downgrading to firebase-tools@8.0.3

[kamaladenalhomsi]

After spending more than one hour playing around with my config files, also I updated my nodejs and firebase-tools to latest, I still had had this error, I fixed it by removing hosting cache in .firebase directory
