Hi Ayoub,
Thank you for reaching out. The above answer is correct. You can only select
fields that are compatible with each other and must specify them individually
in your query.

Of course you can get all fields, but not in a single API-request. The
reason for that, certain field combinations are not allowed.
This is all documented. To see an example of such documentation, here is an
example.
