Failed to import any JSONs to tandoor - also exported once

[simonschaubel]

Hi,
Not sure if this is a bug or I am the bug. I tried to import json formated recipes but failed in all paths. What I tried:

• Import an exported recipe from tandoor export_example.json
• Import Import (gpt made) json recipes / json specification for recipes #3308, this worked in general but does not have any content. examplefromgithub.json

Is there somewhere a schema to check? Why does it not work to import an exported json? Where can I check a detailed error message?

Here are files I tried
