User Table getting a runtime exception

I’ve been trying to access my Users data table, and this error keeps popping up:

“Could not perform persistence operation: java.lang.RuntimeException: Failed to load RelatedUserDataTableColumn for com.backendless.datamodel.UserDataTableRelation from database”

This started happening after I created a relationship in one of my data tables to the Users table, but I deleted that column after I found no use for it a few minutes after. So right now there’s no data table with a relationship to anything. I don’t see anything inside the Users table either.

Thank you!

Hi Kate,

It is working now. Thank you for the quick response.

Hello, I have the same problem with my Backendless application.
I think that my situation is similar, so any support given would be welcome.

My App ID is 44F49D72-5C50-B717-FF89-0D3DE93A7B00


Nevermind, problem solved!

I have the exact same issue with my Backendless app.

Is there a way to solve this issue without having to put my app ID here ? (Maybe an email address ?)
This problem occurs when you delete a table with a relation to the Users table.

We need to know the APP id to be able to resolve it from our side. You can email it to and cross reference this topic.
