This can happen if the field is Required, but no value is supplied.
It can also happen if the field's Allow Zero Length property is set to No
(as it should be), but you attempt to add a zero-length string instead of a
Null.
And there is a Validation Rule for the table (in the Properties box in table
design), as well as for the fields.
