Issue with deploying Firebase Function in Flutter app

I encountered an issue while trying to deploy a Firebase function for a Flutter application that I am developing in Android Studio. The error message I received during deployment is shown below. Can someone please advise me on how to resolve this?

Running command: npm --prefix "$RESOURCE_DIR" run lint

functions@ lint /Users/johnny/Downloads/flutterApp5/functions eslint .

There seems to be an eslint error present. Take note of the following error messages.

Running command: npm --prefix "$RESOURCE_DIR" run lint

functions@ lint /Users/johnny/Downloads/flutterApp5/functions eslint .

/Users/johnny/Downloads/flutterApp5/functions/index.js 18:5 error Expected catch() or return

To resolve this issue, you need to make changes in your code to address the error. Alternatively, consider adjusting the promise/catch-or-return and promise/always-return rules from being categorized as error to warn within your .eslintrc.json configuration file.

Additionally

The

npm --prefix "$RESOURCE_DIR" run lint

command corresponds to the functions.predeploy setting found in the firebase.json file.

Here's an example:

{
...
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint",
      "npm --prefix \"$RESOURCE_DIR\" run build"
    ]
  },
....
}
