Hello,

How can I address this?

The problem was due to I created an attribute named “active”.
Is it a possibility to delete the cash memory?

Also now I have this error:

How did you define the attribute?
Could you provide the entity source code?

I defined the attribute in Entity designer / New.
However I solved the issue by changing the PostgreSql database with a fresh new one.
I encountered some errors when database made the updates…
Thank you!
