Angular reactive form hasValidator return false for custom validator function

[Mithun-codes]

`import { AbstractControl, ValidationErrors, ValidatorFn } from '@angular/forms';

export function trimValidator(minlength: number, maxlength: number): ValidatorFn {
return ({ value }: AbstractControl): ValidationErrors | null => {
const trimValue = value?.trim() || '';
if (trimValue.length < minlength) {
return { minlength: true };
} else if (trimValue.length > maxlength) {
return { minlength: true }; }
};
}
`

myform = this.fbgroup({ name: ['', [Validators.required]], description: ['', [trimValidator(10, 3000)]] })

// When i access default validator through hasValidator then i got true but when i pass custom validator functiion to hasvalidator then return me false

// i am checking this in another file (in some custom-directive)
`this.myform.get('name')?.hasValidator(Validator.required) // true

this.myform.get('description')?.hasValidator(trimValidator(10, 3000)) // false why?
