User data ingest not compatible with "enforced references" (Import, CSV mapper, ...)

[labo-flg]

Description

When some entities have the option "Enforce references", we cannot import them from a CSV using our new CSV mappers.
The backend checks for the validity of the gql input and it lacks the mandatory externalReferences.

Environment

5.11.12

Reproducible Steps

1. Create a simple mapper as explained in this comment.

2. Test it with the csv file provided in same comment --> you will get the validation error.

3. Try to import data using this same file and mapper --> it won't work. Backend logs show the same error (frontend shows no feedback, but that's another issue).

Expected Output

?????

That's a good question actually.
Once you enforce references, what is supposed to be possible ?

Not a CSV specific problem for me. Its global to file ingest. Pinging @Jipegien

This is not a bug. Enforced references are not covered by CSV mappers and any other means to import multiple Objects in one shot. This is a really complex problem for a very little subset of advanced users.

We will tackle this, later, in collaboration with end users to find a good trade off.
