I'm trying to add another field value in a document but firebase returns TypeError: n.indexOf is not a function. Here's the code:

async function linkLCSN(cor, sn) {
  try {
    await setDoc(doc(db, "cor", cor), {
      sn: sn,
    }, {merge: true});
  } catch(e) {
    console.error(e);
  }
}

I've already succeeded in doing this way but I don't know why this time it keeps giving me this error. This is the working code:

async function submitToDatabase(name, email, cor, cs, cn, concern) {
    try {
        //Set Datas 
        await setDoc(doc(db, "cor", cor), {
        name: name,
        email: email,
        cor: cor,
        courseSection: cs,
        contactNumber: cn,
        isViewed: false,
        timestamp: serverTimestamp(),
        }, {merge: true});
        const docRef = await addDoc(collection(db, "cor", cor, "concerns"), {
        concernData: concern,
        });
        console.log("Yung betlog nasa:" + docRef.id);
        //Do page changes
        let a = document.querySelector(".concern-main-container");
        let b = document.querySelector(".concern-preview-container");
        a.style.display = "none";
        b.style.display = "block";
    } catch(e) {
        console.error(e);
        //Custom Alert
    }
}

  • This typically means you're calling a writing function with some illegal values. Can you edit your question to: 1) show how db is initialized, 2) log the value of cor and show the updated code and its output, 3) the plete stack trace of the error message you get? – Frank van Puffelen Commented Jan 16, 2022 at 15:48
  • Thank you for your response, I've found out the cause and it was the cor that was giving an invalid value. – MEAries Commented Jan 16, 2022 at 16:26
  • Good to hear that you found the problem Sandren Troy!
