WixData.Update not updating

Hello and thank you in advance for any help! : -)

The Situation:
Search for a record —> the result data populates a form —> user can update the data in the form —> click UPDATE button —> record in the collection is updated.

Problem: update call not updating the record in the collection.
I have checked the permissions: for the dataset on the page = Read/Write and for the collection itself: ANYONE

Also, regarding the QUERY that precedes the update call (in the code below) - there is only one possible match in the collection.

I have hard-coded a few of the fields for testing purposes . Otherwise, all the update data is coming off the form fields.
Here is the OnClick Event code for the Update Button:

// UPDATE record with form contents 

export function UpdateClick(event) {

const options = {
 "suppressAuth": true,
 "suppressHooks": true,
  };

wixData.query("moment-practitioners")
  .eq("naam", origSrchNaam)           // find the record to update based on the ORIG search 
  .eq("postcode", origSrchPostcode)   //  criteria - user may have updated these fields
  .find()
    .then( (results) => {
 if(results.items.length > 0) {

 let item = results.items[0];
        $w("#iNaam").value = item.naam; // updated naam
        $w("#iVoornaam").value = item.voornaam; // updated voornaam
        $w("#iWebsite").value = item.website; // updated email
        $w("#iEmail").value = item.website; // updated website
        $w("#iGemeente").value = item.gemeente; // updated gemeente
        $w("#iPostcode").value = item.postcode; // updated postcode
        $w("#iProvincie").value = item.provincie; // updated provincie
        $w("#iTel1").value = item.tel1; // updated tel 1
        $w("#iTel2").value = item.tel2; // updated tel 2
        $w("#iTxt1").value = item.beroepsactiviteit; // updated beroepsactiviteit
        $w("#iTxt2").value = item.contexten; // updated contexten
        $w("#iTxt3").value = item.specialisatie; // updated specialisatie
        $w("#iTxt5").value = item.bijscholing; // updated bijscholing
        $w("#iTxt6").value = item.mindfulnessBestaatUit; // updated bestaat
        $w("#iTxt7").value = item.trajectOmMindfulnessTrainer; // updated traject
        $w("#iTxt8").value = item.ervaring; // updated ervaring
        $w("#iTxt4").value = item.opleiding; // updated opleiding
        hiddenID = item._ID;
        hiddenFoto = item.foto;
      } else {
 // handle case where no matching items found
 //  DISPLAY no match text on screen
        $w("#tNoMatchMsg").show();
      }
    } )
    .catch( (err) => {
 let errorMsg = err;
    } );

}
