Typegoose, graphql, how to update fields with object types - mongodb

Question

I have a user schema:
#ObjectType()
export class User {
#Field(() => String)
_id: string;
#Field(() => String)
#prop({ required: true })
userName: string;
#Field(() => UserType)
#prop({ enum: UserType })
userType: UserType;
#Field(() => String)
#prop({ required: true })
email: string;
#prop({ required: true })
password: string;
#Field(() => Employee)
#prop({ required: false })
employee: Employee;
#Field(() => Employer)
#prop({ required: false })
employer: Employer;
}
and the employee field has this schema:
#ObjectType()
class Employee {
#Field(() => String)
firstName: string;
#Field(() => String)
middleName: string;
#Field(() => String)
lastName: string;
#Field(() => String)
birthday: string;
#Field(() => String)
address1: string;
#Field(() => String)
address2: string;
#Field(() => String)
phoneNumber: string;
#Field(() => String)
emailAddress: string;
#Field(() => String)
socialMedia: string;
#Field(() => String)
imageLink: string;
#Field(() => [WorkExperiences])
workExperiences: WorkExperiences[];
#Field(() => Personality)
personality: Personality;
#Field(() => Direction)
direction: Direction;
#Field(() => [Education])
education: Education[];
#Field(() => [Certificates])
certificates: Certificates[];
#Field(() => [Awards])
awards: Awards[];
#Field(() => String)
applications: string;
}
I want to create a login form which only adds email and username then redirect to a onboarding page.
I am trying to create a separate mutations with Education, workExperience and other stuffs.
But I am not sure what I am doing.
What I did so far was to create a resolver for example education:
#Authorized()
#Mutation(() => User)
createEducation(
#Arg("input") input: CreateEducationInput,
#Ctx() context: Context
) {
const user = context.user!;
return this.qualificationService.createEducation({
...input,
user: user?._id,
});
}
But I can't seem to create education and throws some error.
I am not sure if I am doing this correctly. Really need help. Thanks guys!
