Does Firebase Function Does not Support Node 18 as its Engine parameter in Package.json file? - node.js

Question

Does firebase function supports node 18 version as its engine parameters in package.json file. I am getting error as " Error: package.json in functions directory has an engines field which is unsupported. Valid choices are: {"node": 10|12|14|16}" when i used Node 18 as engine parameter.
I tried to use node 18 in engine parameter field as
"engines": {
"node": "18"
},
my package.json looks like this:
{
"name": "functions",

The documentation at Set Node.js version says:
Firebase SDK for Cloud Functions 2.0.0 and higher allows a selection
of Node.js runtime. You can choose to run all functions in a project
exclusively on the runtime environment corresponding to one of these
supported Node.js versions:
Node.js 18
Node.js 16
Node.js 14
Upgrade your Node.js runtime
To upgrade your Node.js runtime:
Make sure your project is on the Blaze pricing plan.
Make sure you are using Firebase CLI v9.17.0 or later.
Change the engines value in the package.json file that was created in your functions/ directory during initialization. For example, if you are upgrading from version 16 to version 18, the entry should look like this: "engines": {"node": "18"}
Optionally, test your changes using the Firebase Local Emulator Suite.
Redeploy functions using the Firebase CLI v11.18.0 or later.
