I need some fixing for a Next.JS project

I have a rather simple Dashboard coded in next.js, that requests data in real time from a Glassnode API, does some webscraping, simple processing, displays the data in a spreadsheet, and should be sending notifications to a discord server.

There seems to be a problem with the code itself. Sometimes when accesing the dashboard it shows a client-side exception, which could be related to the way data is retrieved.

I need it to be revised and fixed whether needed.
