[SOLVED] Bad request 400 using Vite React HygraphCMS

In the following code, I run into the issue that I get a 400 BAD REQUEST and pageData doesn't load. When I simply remove the GridText module the code is working fine though. ChatGPT and I are running out of ideas. I hope someone can help.. I added GridText exactly as I did for the other modules, the API looks correct when I test it in the env link.
