Firebase deploy failed even without changing the function from onCallable to onRequest-CodePudding

Error: [functionName(us-central1)] Changing from a callable function to an HTTPS function is not allowed. Please delete your function and create a new one instead.

Any advice and insight is appreciated.

Which version of Firebase CLI (firebase --version) are you using? Last night I updated firebase-tools package to 10.3.0 and functions deployment started giving me the error you mention. I downgraded to 10.2.2 and functions deployment started working as before.

Update: Firebase team confirmed there is an issue with 10.3.0 firebase-tools. They are working on a fix: https://github.com/firebase/firebase-tools/issues/4307

Solution 01:
I think the main problem lies inside whether you are using a valid way to use .env file. Since I just recently have this kind of error. If you do use the .env file inside the structure of your folder, then

You need to declare the path to .env file in all files which uses process.env.VARIABLE_NAME. Example way is like this: require("dotenv").config({path: "../.env"});
After that try to delete all existing Cloud Functions in Google Cloud Console
Try deploy again: firebase deploy --only functions

I added a path to the .env file, since I checked Firebase Cloud Function Logs and it gave me error for all Cloud Functions which uses process.env.VARIABLE_NAME. This .env file must be located inside the root project and placed inside folder functions/. Give it a try. Hope it works.

Solution no. 2:
You should check if there is a variable or function which doesn't give return value, like example below:

const key = async () => {
  const response = await pk.accessSecret("PRIVATEKEY");
  return response;
};

I forgot to add a return value from the variable const key. Therefore I get so many errors like you do in all of my functions. And that errors cause firebase cli to state"
