Answer №1

Issue at Hand

Your current code seems to lack proper type definitions, making it difficult to suggest the most effective way to resolve the problem (ideally, all types should be filled out correctly, especially for class members).

The main error here lies in passing an array of assigned_to with a type of any, when it should actually be of type never for each member.

A Temporary Solution

To temporarily fix this issue, you can cast the variable newUser from type any to type never:

this.userObj.assigned_to.push(newUser as never);

Answer №2

Modify

assigned_to: [];

Into

assigned_to = [];
