Warning 2531: Potential null value found in object

While working on my Android app in Ionic Angular with Firebase, I encountered a problem in Visual Studio Code yesterday. Despite thorough searching, I couldn't find a solution.

Here is the issue

This is the TypeScript code from my user registration page

The error lies in Line 41 with "const id = res.user.uid;"

models.ts

Please assist me!

I attempted to change "const id = res.user.uid;" to "const id = res.user?.uid;", but it did not work.

Answer №1

Ensure that your variable is properly initialized and not set to null. If you are confident that the variable (such as user) will not be null, you can try:

const id = res.user!.uid;

Alternatively, you can suppress the error by adding this line directly after the section of code generating the error:

// @ts-ignore: Object is possibly 'null'.

Another option is to disable null checking in your project's tsconfig.json file (though this is not recommended) like so:

"compilerOptions": {
    ...
    "strictNullChecks": false
  },
