Enabling ESLint during Firebase Initialization can lead to this issue.

If you encounter this problem, you can run ESLint directly by navigating to your main project folder and executing these commands in your terminal:
cd functions && npx eslint . --fix
or
cd functions && node_modules/eslint/bin/eslint.js . --fix
These commands will automatically fix any issues that ESLint can handle. If there are no warnings after running the command, you can proceed to deploy the function without any problems. However, if warnings still persist, you will need to manually address them before deployment.
Note: If you prefer not to use ESLint, you have the option to recreate your project and decline using ESLint when prompted. Alternatively, you can disable ESLint in your current project by editing the firebase.json file and removing the predeploy script that triggers the lint command. Below is a sample of the edited firebase.json:
{
"functions": [
{
"source": "functions",
"codebase": "default",
"ignore": [
"node_modules",
".git",
"firebase-debug.log",
"firebase-debug.*.log"
],
"predeploy": []
}
]
}
To disable ESLint, remove the following block of code from your firebase.json:
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint",
"npm --prefix \"$RESOURCE_DIR\" run build"
]
