Problem with import value to boolen fields from Fields plugin or if this fields is in import model

[Wolvverine]

Problem with import boolen value to fields from Fields plugin.

On import the records that are added are added correctly, when trying to re-import as an update an import error pops up.
The problem is when the field being updated comes from the fields plugin and is of type boolen.

The problem also occurs when updating if a field has been left empty/unchanged in the import file, but is only in the import.

Restoration:

1. add a new field from the fields plugin of type boolen to the asset computer
2. add this field to the import model
3. import of data from csv
4. repeat import to update fields

Version:
Fields - 1.21.11
Datainjection - 2.13.5
GLPI - 10.0.15,10.0.16
