## Observed behavior

## Expected behavior

quand je remplie un formulaire , et que je renseigne les champs obligatoires , et pas les chamaps facultatifs, apprès la validation les champs facultatifs sont remplis par des 1

```javascript
//Create a sageProviders
router.post('/sageProviders', permissionMiddlewareCreator.create(), (request, response) => {
  const recordSerializer = new RecordSerializer({ name: 'sageProviders' });
  const data = request.body.data.attributes;
  console.log("🚀 ~ data:", data)

  if (!regValidateSiret.test(data.siret)) {
    response.status(400).send('Le SIRET contient des espaces ou des caractères autres que numériques. Merci de corriger.');
  }
  const body = {
    matricule: '',
    mail: data.email,
    city: data.site_ville,
    street: data.street,
    company_name: data.raison_sociale,
    street_number: data.street_number,
    phone_number: data.telephone,
    siret: data.siret,
    zip_code: data.site_codepostal
  };

  axios.post(`${API_URL}/forest_admin/sage_create_provider`, body, {
    headers: {
      'Authorization': `Bearer ${process.env.ACCESS_TOKEN}`,
      'X-CURRENT-USER-EMAIL': request.user.email
    },
  }).then(async postResponse => {
    console.log("🚀 ~ postResponse:", postResponse)
    response.send(
      await recordSerializer.serialize(
        {
          id: postResponse.data.fournisseur.matricule,
          ...postResponse.data.fournisseur
        }
      )
    );
  }).catch(err => {
    if (err.response?.data?.error?.message) {
      response.status(400).send(err.response.data.error.message);
    } else if (err.response?.data?.error) {
      response.status(400).send(err.response?.data?.error);
    } else {
      response.status(400).send('Erreur inattendue, veuillez contacter votre administrateur.');
    }
  });
});

Hi @Soufiane ,

I did not really understand when in your code the data is filled by ‘1’ ?
