If you’re getting the error “TS2531: Object is possibly ‘null'”, it means that the TypeScript compiler is unable to determine whether a particular object is null or not at the point where you are trying to access a property or method on it. This can occur when you are trying to access an object that may be null or undefined, such as when you are trying to access a property of an object that may not exist.

To fix this error, you will need to ensure that the object is not null or undefined before trying to access any of its properties or methods. One way to do this is to use the “nullish coalescing operator” (??) to provide a default value for the object if it is null or undefined. For example:

const obj = someObject ?? {};

This will ensure that obj is always an object, even if someObject is null or undefined. You can then safely access properties and methods on obj without worrying about the error “TS2531: Object is possibly ‘null'”.

Alternatively, you can use the “optional chaining operator” (?.) to safely access properties and methods on an object that may be null or undefined. For example:

const value = someObject?.someProperty;

This will return undefined if someObject is null or undefined, rather than throwing an error.

It’s also important to make sure that you are properly handling null and undefined values throughout your code, as failing to do so can lead to this error and other issues.
