fix: null data checks

[JaeAeich]

Description

While fetching the data from notion, if the data is null or empty, there currently aren't any checks to gracefully handle these issues, which breaks the site. Add check on data to validate it before using a map, filter etc finc on them.

Info

Some of such functions are in utils such as solution.js and contributor.js. Check for more if present in the repo 🙂 .

I want to solve this issue can you please assign me ? also after adding the null check if the data in null what do we need to display on the UI part ?

Thanks @Chaitanya674 - please go ahead. As for what to show if the data is null - I guess it depends on what is missing. I would propose that the first thing to do is to look through the codebase and enumerate the cases here in this issue, possibly as a table together with a proposal how to gracefully handle the missing data, i.e., what to show instead.

We can then discuss that proposal before you start implementing it.

My bad, just seen that you already provided a PR :)
