[ PRs Welcome ] Error when fetching page data

[Tumpelox]

I have followed all needed steps but I get this error.

> 16 |     const contentSections = page.data[0].attributes.contentSections;
     |                                         ^
  17 |
  18 |     return contentSections.map((section: any, index: number) => sectionRenderer(section, index));
  19 | }

If I console log the page variable I get this:

{
  data: [],
  meta: { pagination: { page: 1, pageSize: 25, pageCount: 0, total: 0 } }
}

I noticed that params.lang will get value 'favicon.ico' but when request made with getPageBySlug('home', 'en'); I get correct data

{
  data: [ { id: 1, attributes: [Object] } ],
  meta: { pagination: { page: 1, pageSize: 25, pageCount: 1, total: 1 } }
}

But still there is this and nothing shows up at the browser

wait  - compiling /[lang]/page (client and server)...
event - compiled successfully in 465 ms (276 modules)

Data seeding didn't work so I filled it manually (page with the home slug and global)
