Can't insert data into collection

Hi all - I am trying to insert data into a collection on my site and it is failing. I’ve used the code on another site I have and it worked. On the pages where I have the import wixdata api, I get an initial error of ‘Failed to load initial data’. I fear that is a reason I am not able to do this. Has anyone else had that problem?

Here is my code to try and insert data into a collection:

// I have a field populated with the current user ID on page
// My database is called #membersDatabase or Members. I’ve tried both and neither work.
// Each time I try to insert the data, it correctly prints the toInsert variable but says ‘Your upload failed!’

export async function next2_click(event, $w) {

let toInsert = {
“uniqueUserId”: $w(“#uniqueUserId”).value,
“type”: “user”,
};
console.log(toInsert)
wixData.insert(“Members”, toInsert)
.then ( (results)=>
{
let item = results;
console.log(“You uploaded to database!”);
})
. catch ( (err)=>
{
let errorMsg = err;
console.log(“Your upload failed!”);
});

Thanks in advance!

On the last 5 lines, replace them with this:

.catch ( (err)=> {
   let errorMsg = err;
   console.log(err);
});

This will print the actual error message and you will know what is going wrong
