The conversion to ObjectId was unsuccessful for the user ID

Question

The conversion to ObjectId was unsuccessful for the user ID

I'm looking to develop a feature where every time a user creates a new thread post, it will be linked to the User model by adding the newly created thread's ID to the threads array of the user. However, I'm running into an issue when trying to create a thread. Any help would be greatly appreciated.

Failed to create thread: Thread validation failed: author: Cast to ObjectId failed for value "user_2TXrt6taAgNcj0meuTHUEuxQ364" (type string) at path "author" due to "BSONError"

I have confirmed that the "author" field is being assigned correctly and corresponds to the expected data type, which is ObjectId in this instance.

Hey there, I am also working on a similar threads project. Make sure to include the following segment in PostThread.tsx within the post thread:

const [userData, setUserData] = useState(null);

useEffect(() => {
  // Fetch user data
  fetchUser(userId)
    .then((user) => {
      setUserData(user);
    })
    .catch((error) => {
      // Handle error
    });
}, [userId]);

Remember to update the author field to use userId.id while keeping the rest unchanged.

const onSubmit = async (values: z.infer<typeof ThreadValidation>) => {
  await createThread({
    text: values.thread,
    author: userId._id,
    communityId: null,
    path: pathname,
  });
});

The main issue here was that you were utilizing the custom id field from your User schema instead of the MongoDB-generated _id field. To fix this problem, make sure to retrieve and utilize the actual _id value from your user data when creating a thread.

According to the error message, user_2TXrt6taAgNcj0meuTHUEuxQ364 is not a valid object ID. You must update your mongoose schema so that User is defined as type String

Avalid object id typically looks like 638c6c2875345eefb8aafa28

In this scenario,

author: { 
type: String,
ref: "User"
required: true, 
},

It's important to also adjust the User Schema accordingly.

Your database schema is accurate; however, an error has occurred.

The value "user_2TXrt6taAgNcj0meuTHUEuxQ364" could not be cast to ObjectId.

The ID user_2TXrt6taAgNcj0meuTHUEuxQ364 is not a valid Mongoose identifier and may be causing issues when querying MongoDB

Perhaps the solution is quite simple - just review your create-thread page.tsx file and ensure you are passing the correct id:

return (
  <>
    <h1 className="head-text">Create thread</h1>
    <PostThread userId={userInfo._id} />
  </>
);

I mistakenly used id instead of _id, which caused the issue of passing the inner userId instead of the ObjectID.
