Property ‘tobeinthedocument’ does not exist on type

by

The error message “property ‘tobeinthedocument’ does not exist on type” typically occurs when you try to access or use a property that has not been defined or declared in the given type or class. This usually happens in statically-typed programming languages like TypeScript.

To resolve this error, you need to make sure that the property you are trying to access actually exists in the type or class. Here are a few possible explanations for this error and how to fix them:

1. Misspelled Property Name:
Double-check the spelling of the property you are trying to access. Make sure it matches the declaration of the type or class. For example, if you have a class called “Person” with a property “name”, ensure that you are using “name” correctly and not misspelling it as “tobeinthedocument”.

class Person {
  name: string;
}

const person = new Person();
console.log(person.tobeinthedocument); // Property 'tobeinthedocument' does not exist on type 'Person'.

2. Missing Property Declaration:
If you are working with an external library or module, make sure to import the necessary types. If the property is not declared in the original type or class, you might need to extend or modify it to fit your specific requirements.

interface Person {
  name: string;
  age: number;
  // 'tobeinthedocument' property is missing in the original definition.
}

const person: Person = { name: "John", age: 25 };
console.log(person.tobeinthedocument); // Property 'tobeinthedocument' does not exist on type 'Person'.

3. Incorrect Type Assertion:
If you are explicitly providing a type assertion (using the ‘as’ keyword) to a variable or object, ensure that the asserted type actually contains the property you are trying to access.

interface Person {
  name: string;
  age: number;
}

const person = {} as Person;
console.log(person.tobeinthedocument); // Property 'tobeinthedocument' does not exist on type 'Person'.

It is important to understand the structure and definition of the types and classes you are working with. Review the documentation or type definitions, and make sure you are using the correct properties and types to avoid this error.
