psycopg2.errors.NotNullViolation: null value in column "name" of relation "entity" violates not-null constraint
DETAIL:  Failing row contains (256517, E31, null, null, 2025-04-09 13:02:04.336508, null, null, null, null, null, null, null, null, external_reference).

The problem is the MLStripper() class in the sanitize() function. It sees the & with following characters without spaces as HTML and returns None.
The simplest solution would be to add a replace function before and after the sanitizer:

string = string.replace('&', '&')
stripper = MLStripper()
stripper.feed(string)
sanitized = stripper.get_data().strip()
sanitized.replace('&', '&')

But I don't know where this could break something.
And we should not forget to adapt one test case with something like 'Hänsel &Gretel'.
