Turn In API giving no response - google-workspace

Question

I'm trying to integrate google classroom API where student can submit their work on a particular
assignment and then update the state to hand in/turn in. I'm using turn in API endpoint but the API
doesn't update the state nor return any response.
import { Injectable } from '#nestjs/common';
import { ConfigService } from '#nestjs/config';
import { google, classroom_v1, Auth } from 'googleapis';
#Injectable()
export class GoogleApiService {
oauth2Client: Auth.OAuth2Client;
classroom: classroom_v1.Classroom;
constructor(private configService: ConfigService) {
const clientId = this.configService.get('GOOGLE_CLIENT_ID');
const clientSecret = this.configService.get('GOOGLE_SECRET_KEY');
const redirectUrl = this.configService.get('GOOGLE_REDIRECT_URL');
this.oauth2Client = new google.auth.OAuth2(
clientId,
clientSecret,
redirectUrl,
);
google.options({
http2: true,
});
this.classroom = google.classroom({
version: 'v1',
auth: this.oauth2Client,
});
}
setRefreshToken(token: string) {
this.oauth2Client.setCredentials({
refresh_token: token,
});
}
async turnIn(courseId: string, courseWorkId: string, submissionId: string) {
try {
const turnInParam: classroom_v1.Params$Resource$Courses$Coursework$Studentsubmissions$Turnin =
{
courseId,
courseWorkId,
id: submissionId,
};
const res =
await this.classroom.courses.courseWork.studentSubmissions.turnIn(
turnInParam,
);
return res;
} catch (error) {
console.log(error);
return false;
}
}
}
after this nothing executes.
const res =
await this.classroom.courses.courseWork.studentSubmissions.turnIn(
turnInParam,
);
