I created Firebase Cloud Functions in VS Code using Typescript and there are no errors shown in VS Code. But when I deploy my firebase code, I get several error messages. Why do I get all these error messages and why does VS Code not show a single one? And how I can fix it such that VS Code shows me the errors?
The Errors:

CodePudding user response：
This occurs when you've enabled the ESLint on Firebase Initialization.
You can run the ESLint directly by heading into your main project folder then execute these commands on your terminal:
cd functions && npx eslint . --fix
or
cd functions && node_modules/eslint/bin/eslint.js . --fix
The above commands will fix what ESLint can fix automatically. If no warnings are caught after running the command, then you can now deploy the function without having an issue. If you have still warnings then you must manually fix it before deploying the function.
Note: If you don't want to use ESLint, you can re-create your project, choose not to use ESLint when it prompts you. Or you can disable it in your current project by editing your firebase.json file and removing the predeploy script that runs the lint command. See sample firebase.json below:
{
"functions": [
{
"source": "functions",
"codebase": "default",
"ignore": [
"node_modules",
".git",
"firebase-debug.log",
"firebase-debug.*.log"
],
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint",
"npm --prefix \"$RESOURCE_DIR\" run build"
]
}
]
}
Remove these block of code:
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint",
"npm --prefix \"$RESOURCE_DIR\" run build"
]
