Dataset Save Error: save - "This item already exists" - NEEDS SOLVING

I need help on my sites lightbox. I have connected a dataset to the lightbox but for some reason when I click my button to save the information to the database it shows that error in the title. Why is this happening??

Checks that I went through:

  • Dataset is in “Write-Only” mode
  • Code is exactly how it is from the reference page
  • Did two error checks. The first error check (i.e., $w(“#recipesdata”).onError) showed up undefined for both of the consol.log’s below. Then the second error check that I put on the save function (i.e., . catch ((err)) , it said that there was an item that already existed in my dataset. Which I checked also and didn’t find any duplicates.
  • Checked for duplicates in the dataset with the current items ID

Code (below):

let item = $w("#recipesdata").getCurrentItem()
 
let toSave = {
 "name": $w("#recipename").value,
 "teaser": $w("#recipeteaser").value,
 "description": $w("#recipedescription").value,
 "prepnumber": $w("#recipetime").value,
 "preptime": $w("#recipetimedescription").value,
 "servings": $w("#recipeservings").value
            }
            $w("#recipesdata").setFieldValues(toSave)

            $w("#recipesdata").onAfterSave(() => {
                console.log("id found - processing after save")
                recipeId = item._id
                console.log(recipeId)
                changestep("two")
                filterdirectionsonrecipeID()
                filteringredientsonrecipeID()
                $w("#reviewtime").text = $w("#recipetime").value + " " + $w("#recipetimedescription").value;

            })
            $w("#recipesdata").onError((operation, error) => {
 let errorOp = operation; // "save"

 let errorCode = error.code; // "DS_VALIDATION_ERROR"

 let errorMessage = error.message;
 // DatasetError: Some of the elements validation failed
                console.log("id found - error")
                console.log(errorOp)
                console.log(errorCode)
                console.log(errorMessage)
            })
 
            $w("#recipesdata").save()
            .then((items) => {
 let fieldId = items._id;
                    console.log(fieldId)
                })
                .catch((err) => {
 let errMsg = err;
                    console.log(err)
                });

Please help me find out why this is happening to my site. I am really trying to save the information.
