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!

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.

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

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?

let buffer = req.file.buffer; let uint8Array = new Uint8Array(buffer); await pdfParse({ data: uint8Array }).then((data) => { console.log(data.text); res.status(200).send(data.text, 'PDF file uploaded and converted to text'); })
