Firebase Error - Too many arguments provided to Query.startAt()

I am trying to figurate why am I getting this error

FirebaseError: Too many arguments provided to Query.startAt(). The number of arguments must be less than or equal to the number of Query.orderBy() clauses

with this code:

const query = firebase
  .getDatabase()
  .collection("users")
  .where("premium", "==", true) // get premium users
  .where("totalPosts", ">", 0); // that have posted some music


...

return query
    .startAt(0)
    .limit(1)
    .get()
    .then((snapshot) => {
          ...
    );

As you can see, I am trying to get premium users that have posted some music. I am using the where and startAt clause, and not the orderBy.

What am I doing wrong?

Thanks!

Read the error message carefully:

The number of arguments must be less than or equal to the number of Query.orderBy() clauses

Your code doesn't show any orderBy clauses at all, so the number in this case is 0. But you provide 1 argument to startAt(). You should actually provide an orderBy clause, to be specific. It must match the field of your range query:

const query = firebase
  .getDatabase()
  .collection("users")
  .where("premium", "==", true) // get premium users
  .where("totalPosts", ">", 0)  // that have posted some music
  .orderBy("totalPosts")

Then, your pagination should repeat the exact same query, only this time with startAt to tell it where to pick up:

return query.startAt(0);
