No Invitations ID

I have many google classroom invitations and I want to accept all of them through google app script using

Classroom.Invitations.accept("courseId");

but then I get no data back...

so I tried listing all my invitations using

Classroom.Invitations.list({"userId":"my_email"}); 

and still I get no data back...

I am very sure that my google classroom is full of unaccepted courses

Modification points:

• In your script, an error occurs at var teacherEmails=(john.doe@gmail.com,jane.doe@gmail.com);.
• I thought that your script might be for a python script. If you want to use this method using Google Apps Script, it is required to modify it.

When these points are reflected in a Google Apps Script, how about the following sample script?

Sample script:

Before you use this script, please enable Classroom API at Advanced Google services.

function myFunction() {
  const courseId = "###"; // Please set your course ID.
  const teacherEmails = ["john.doe@gmail.com", "jane.doe@gmail.com"]; // Please set email addresses.

  teacherEmails.forEach(userId => {
    const res = Classroom.Invitations.create({ courseId, userId, role: "TEACHER" });
    console.log(res)
  });
}

Reference:

• Method: invitations.create
