Firestore error 'Updating a non-existent query'

Sorry for my poor English.

When executing code like the following, an error like the image appears.

@firebase/firestore: - "Firestore(5.5.0): FIRESTORE(5.5.0) INTERNAL ASSERTION FAILED: Updating a non-existent query"

@firebase/firestore: - "Firestore(5.5.0): INTERNAL UNHANDLED ERROR: "

Unhandled Promise Rejection: Error: FIRESTORE(5.5.0) INTERNAL ASSERTION FAILED: Updating a non-exixtent query

Error: FIRESTORE(5.5.0) INTERNAL ASSERTION FAILED: Updating a non-existent query

firestore_error

const db = firebase.firestore();
const dammyRef = db.collection('dammy');

dammyRef.where('num', '>=', 18).where('num', '<', 30).get()
  .then((querySnapshot) => {
    querySnapshot.forEach((doc) => {
      console.log(doc.data());
    })
  });

However, this error occurs only when using iPhone's Safari or Chrome. There is no error in Chrome on the PC version.

The version of Firebase, "firebase": "^ 5.5.0",

Please tell me the reason why this error occurs.

Thank you.
