I found the video very useful. Would it be possible to do a video with a more complex structure using Next.js 13 and making debugging? This would help a lot since I regularly get stuck with errors and I don't know how to handle those errors or interpret them. Thank you!

[kajetankowalski]

Exactly what I was looking for, thank you! :D. And as a sidenote, you're editor theme looks neat, what theme is it?

Please make an advance level error handling video in a React app, handling errors according to different http response statuses with some efficient advance way. Curious. Thanks for this video.

Can you make a video on how to setup env vaariable inside a react native expo app for both development and when the app is pushed for production to the app stores.

[jamshediqbal]

I must say try~catch block should be used when you have async await syntax

[usmanmarkaz]

​plz make full stack Netflix clone in React native

Giving example of try-catch for type errors instead of recommending using typescript seems strange.

Error: Invalid parameter in getDocument, need either Uint8Array, string or a parameter object
this error is coming up again while parsing pdf to text
// let buffer = req.file.buffer;
// console.log(buffer);
// await pdfParse(buffer).then((data) => {
// console.log(data.text);
// res.status(200).send(data.text, 'PDF file uploaded and converted to text');
// })
where have I made the mistake?
