Error 500 Cannot read properties of null (reading 'data')

I am building a project using Nuxt3 and Prismic. Everything was working until I changed the content of one of my keytext on the homepage. Nuxt is suddenly no longer able to fetch data from my Prismic repo from any of my pages. My website is on a Ubuntu server and it stopped working at the same moment than locally. I tried deleting cookies and watched for any Nuxt related problems but I dont think so.

Cannot read properties of null (reading 'data')

Thank you in advance !

Seems like it is now working again !
I did nothing except creating empty new Prismic repository to test if it was related to my nuxt project.

It suddenly stopped working and behaves like the repo is not accessible.

We can run some specific queries like tags, but if we try to get the document then got errors.
Did you've made any updates to getting documents by query?
In the beginning, there were 500 internal server errors. After 403 erros with requesting token (what is not our case, we are not using tokens). And in the end 404.

I cannot query my repo.
On the web query (graphql) page, first I was getting internal_server_error and now I'm getting just open and closed quotes (""). On api web query I get error written in the result section.

From backend I get

statusText: 'Not Found'

        [Symbol(map)]: [Object: null prototype] {
          'content-type': [ 'application/json' ],

In the web graphql api I just got

TypeError: Cannot read properties of undefined (reading 'refs')

I just want to mention that the query is basic

query {
  allProduct_familys {
    edges {
      node {
        _meta {
