Problem:
The code was causing a TypeScript error because clearInterval expects an argument of type number | undefined, but this.timerInterval was typed as NodeJS.Timer. This mismatch was causing the following error:
No overload matches this call.
Overload 1 of 2, '(intervalId: string | number | Timeout | undefined): void', gave the following error.
Argument of type 'NodeJS.Timer' is not assignable to parameter of type 'string | number | Timeout | undefined'.
Solution:
The issue was resolved by updating the type of timerInterval to NodeJS.Timeout | undefined, which is the correct type for the return value of setInterval in a Node.js environment. This ensures compatibility with clearInterval and eliminates the TypeScript error.
This change ensures that the type of timerInterval is compatible with what clearInterval expects, preventing type errors during compilation.
