    addDoc is an asynchronous operation. You need to use the await keyword to halt execution of your code until the document is added. Otherwise docRef will not represent your document.

    try {
  const docRef = await addDoc(collection(db, "users"), {
    name: "Alan",
  });
  console.log('yyyyy');
  console.log("Document written with ID: ", docRef.id);
} catch (e) {
  console.error("Error adding document: ", e);
}

    try that

    try {
  console.log
  const docRef = addDoc(collection(db, "users"), {
    name: "Alan",
    //middle: "Mathison",
    //last: "Turing",
    //born: 1912
  }).then(res => {
    console.log('yyyyy');
    console.log("Document written with ID: ", docRef.id);
  });
  
} catch (e) {
  console.error("Error adding document: ", e);
