wixUsersBackend.register() error

The call used to work fine in the past, but shows the following error now, anyone else facing this?:

{"message":"member with email [email@addre.ss] already exists in collection: 863b404c-bcc7-4432-bbbf-320b34fb5a96 (-19995)","details":{"errorCode":"-19995"}} (403)

When I look in the contacts collection, I see the entries added twice.

Here is my code :
export function processEmailRegistration(email, password) {
return new Promise((resolve, reject) => {
wixUsersBackend.register(email, password)
.then((results) => {
resolve(results);
})
.catch((error) => {
console.log("Registration error ", error);
reject(error)
})

}) 

}

You cannot register user using a “used” emails. Used emails included your Wix account as well. For contacts, it is different from Site Members, please see the wix CRM backend API to create contact (not site member that can login). Create contact can be using duplicated emails.

I am not using email addresses already registered, by “used” if that is what you mean.
I am using fresh(unused) mail ids, I get the same error.

Can you open the “Members/PrivateMembersData” database in your editor to check if it is already exist?

If this issue still occurs, please post your FULL code here

Here is my FULL server side code :
export function processEmailRegistration(email, password) {
return new Promise((resolve, reject) => {
wixUsersBackend.register(email, password)
.then((results) => {
resolve(results);
})
.catch((error) => {
console.log("Registration error ", error);
reject(error)
})

}) 

}

So it’s not just me! How are we supposed to view this collection?

That doesn’t appear to be EditorX. If it is, how do you get that layout?

Got the same problem with a new fresh email say already exist!
