Hi @Gunjan, In 99% cases this is related to some mess in Users collection’s properties or in the Login/Signup form (leave 1% for Adalo glitches). How your Users collection is structured? How did you set up your Sign Up form? As a test - what if you add a new temporary screen, add a sign-up form there, set it up (with email and password) - do you see the same effect? Best regards, Victor. ---

Hi Victor, I’m having the same issue. My form only requests Name, Email and Password. What kind of “mess” in the properties are you referring to? Thanks! Afonso ---

Hi @afonso, There are 4 built-in properties in Users collection: Email, Password, Username and Full Name. They can’t be deleted by design. The only property which is checked for uniqueness is Email, meaning that if one tries to create a user with the same value in Email field, this will fail. Just in case, adding a space before/after isn’t checked, which creates another potential headache for support 😉 However (and unfortunately in my point of view) these properties could be (a) **renamed** and (b) **rearranged** together with other **custom-created** properties. I’ve seen that quite a lot of times. The issue is, that if app Maker renames “Email” property to something else (e.g. phone), and renames other “built-in” properties, it will be quite difficult to find which exact property is that “built-in email” which is checked for uniqueness. Especially if Maker decided to create another property and name it “Email”. The only hint is that built-in properties couldn’t be deleted (you see the lock on the right side). At the same time **any** first property in the collection couldn’t be deleted, which adds some intrigue when you try to find the original email property. So imagine Users collection with 20+ various properties, original properties rearranged and renamed, and you are creating the form to log in / sign up a user. This is what I call a “mess” 🙂. If you’re 100% sure you don’t have such case and you’ve set up your sign-up form correctly - inspecting browser error console can give a hint about the error’s reason. Sometimes Adalo DB has glitches. Hope this helps 🙂 Best regards, Victor. ---

Thanks Victor! My issue seem to be related to no. of records. I reached max-limit 200 records, once I deleted some then this issue was gone. ---

@Gunjan thanks for following up. So it seems Adalo doesn’t handle the error message correctly :-/ Best, Victor. ---
