"TypeError: Cannot read properties of undefined (reading 'text')" #455
Comments
🤖 Hey there, @ovpn-dev! Good to see you again in the issues section. Hope you're having a great coding day! The error you're encountering, "TypeError: Cannot read properties of undefined (reading 'text')", typically occurs when you're trying to access a property of an object that is undefined. In the context of the gpt4-pdf-chatbot-langchain repository, this error could be happening at the line where you're trying to access the 'text' property of the 'data' object: message: data.text, This error could be due to a few reasons:
To debug this issue, you could add more error handling and logging to your fetch request to see what the response from the server is: try {
const response = await fetch('/api/chat', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({
question,
history,
}),
});
if (!response.ok) {
throw new Error(`HTTP error! status: ${response.status}`);
}
const data = await response.json();
if (!data || !data.text) {
throw new Error('Unexpected response from server');
}
// rest of your code...
} catch (error) {
console.error('Fetch error:', error);
} This will give you more information about what might be causing the 'data' object to be undefined. You can find the relevant code in the pages/index.tsx file. Also, there is error handling implemented in the fetch request to '/api/chat' in the gpt4-pdf-chatbot-langchain codebase. The code is wrapped in a try-catch block. If any error occurs during the execution of the code within the try block, the catch block will be executed. The error will be logged to the console and a response with a status code of 500 will be sent back to the client with the error message. You can find this in the pages/api/chat.ts file. I hope this helps! If you have any more questions or need further clarification, feel free to ask. SourcesThis response is meant to be useful and save you time. It is not meant to be a precise solution, but rather a starting point for your own research. Help me be more useful! Please leave a 👍 if this is helpful and 👎 if it is irrelevant.

Ingesting the pdf documents work fine. but after running "npm run dev" and the ui opens up on localhost. sending a message brings up this error under the input box "Cannot read properties of undefined (reading 'text')". Please help. Pointing me in the right direction would be amazing.
