I'm running into issues inserting an entity into PostgreSQL. I have a column is_deleted that is a not null boolean type. When I try to perform an insert I recieve the following error in my log "ExecInsert: Fail to add null value in not null attribute is_deleted". The value of the is_deleted or rather isDeleted property in my class is set to false and the log even tells me the value it is trying to insert for that column is false but I still get the error.

Log snippets:
