Problem:
I'm encountering a "React has detected a change in the order of Hooks called by HomePage" error after refreshing my page. The error occurs specifically on the HomePage
component. The application works as expected after logging in, but when I refresh the page, I receive the following error:

Error Component Stack at HomePage (HomePage.js:14:47) at App (_app.js:6:31)
Code:
Here's the relevant code snippet from my HomePage.js
component:
useEffect(() => {
if (!messages || messages.length === 0 || !session?.user?.id || !currentConversationId) {
return; // Ensure useEffect exits early if dependencies are missing
}
const saveMessage = async () => {
const lastMessage = messages[messages.length - 1];
if (!lastMessage) return;
try {
await fetch(
`http://localhost:3001/api/conversations/${currentConversationId}/messages`,
{
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({
userId: session.user.id,
sender: lastMessage.sender,
message: lastMessage.text,
}),
}
);
} catch (error) {
console.error("Error saving message:", error);
}
};
saveMessage();
}, [messages, session?.user?.id, currentConversationId]);
const handleSend = async () => {
if (!input.trim()) return;
const newMessage = { sender: "user", text: input };
setMessages((prev) => [...prev, newMessage]);
setInput("");
try {
let conversationId = currentConversationId;
if (!conversationId) {
const response = await fetch(
"http://localhost:3001/api/conversations/new",
{
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ userId: session.user.id }),
}
);
if (!response.ok) throw new Error("Failed to create new chat");
const data = await response.json();
conversationId = data.id;
setCurrentConversationId(conversationId);
await new Promise((resolve) => setTimeout(resolve, 0));
}
const aiResponse = await fetch("http://localhost:3001/api/generate", {
method: "POST",
headers: { "Content-Type": "application/json" },
body: JSON.stringify({ prompt: input }),
});
const data = await aiResponse.json();
const aiMessage = { sender: "ai", text: data.message };
setMessages((prev) => [...prev, aiMessage]);
} catch (error) {
console.error("Error in handleSend:", error);
}
};
I expected the saveMessageToDB
function to wait for currentConversationId
to be available before making the API call, ensuring messages were associated with the correct conversation.
