Im following the netflix-clone tutorial with moralis, react and Web3UIKit and in the part where we can fetch data from the database to see myList in our Home.js component in the use effect, i got this error message in the console: âError: You need to call Moralis.start with an applicationId before using Moralisâ.
You can use const { isInitialized } = useMoralis() and set that in your useEffect to only run fetchMyList if (isInitialized) is true.
In your example, it will run even if account isnât valid e.g. null, so likely before the server connection has happened.
Thats worked. Thank you so much!
This is my new useEffect
How are you disconnecting? Do you get any error when you try and connect again?
also from which table ?
With a connectButton from the Web3UIKit. Yes I get the error that I mentioned in the previous post
From the user class. I create a new attribute call myList to store an array of movies, and then make a request from the client to fetch the data

Your fetchMyList will run if Moralis has initialized even if account isnât valid e.g. switches from a valid address to null, this would explain the POST error.
You can add && account to your if statement for running fetchMyList(), you should also add isInitialized to your useEffect dependencies.
I tried, but the error still persist. I have to delete the colum created in the user class to connect the wallet again.

Are you not updating the attribute? So youâre creating it and then youâre trying to create it again. Can we see this code. I would think getMyList should only read data or this list.
I have this cloud function that reads data from the database but can update data too
Ok, I imagine if you were to put a button in your frontend that calls this cloud function separately, the same error will happen without connecting/disconnecting the wallet, given that you need to delete the column to get it working again.
You should also look at separating out your cloud functions e.g. when user connects, getMyList only reads the list.
I am calling this cloudFunction on the useEffect hook and it supposed to be trigger only if there is an Authenticated user and an account. How could I fix that?
Not sure what you mean, getMyList will only work when the user is valid as it requires the address or addrs. That should be fine.
I mean, how can I separate out my cloud function to only call getMyList when user connects.
You can make a cloud function that only gets the list or edit your existing one. And then use another cloud function for updating.
You can check the user object in request parameter from that cloud function. In case that it helps you.
