Error message "EngineVersion"

BIZ TMS XData
1
i check my server on the browser "http://localhost:2001/tms/Xdata" and the result is 

{
    "value": [
        {
            "name": "Users",
            "url": "Users"
        }
    ]
}

but when i am trying to check the data of Users table "http://localhost:2001/tms/Xdata/Users"  i get the error

{
    "error": {
        "code": "PropReadOnly",
        "message": "EngineVersion"
    }
}

Any Help?

That error hints about a property EngineVersion which is read only. There is no such property in XData framework. Is that something from your TUsers entity? Don't you have a readonly property there? If yes, just make it writeable.

it is related to elevatedb database component which has EngineVersion which is string property display the version of the database, Nothing to do with it.

is it Bug?
5

i test the same code with ms sql server (Direct Mode) and it is working well, so i think it is bug.

6

Are you using latest XData and Aurelius versions?

7
i reinstalled the latest trail version and the error changed to 
{
    "error": {
        "code": "DatabaseError",
        "message": "Database name 'myDataBase' already exists"
    }
}
so should i create the the database component (TEDBDatabase) manually by the code and give it unique name ?  
it behave different from firedac Adapter, with Firedac i just follow the wizard and every thing go well.

Please try to set the following property in your TAureliusConnection component:



AureliusConnectino1.CloningMode := TCloningMode.Owner;
9
i do it and get 
{
    "error": {
        "code": "ReadError",
        "message": "Error reading WSession.SessionName: Session name 'WSession' already exists"
    }
}

which WSession is TEDBSession componnet.
i create the TEDbDatabase Component By code and give it unique Name and every thing go well

class function TElevateDBElevateDBConnection.CreateConnection: IDBConnection;
var
  Conn: TEDbDatabase;
begin
  Conn := TEDBDatabase.Create(Nil);
  Conn.SessionName  := ElevateDBElevateDBConnection.WSession.SessionName;
  Conn.Database     := 'Demo'; // Database To Connect  to
  conn.DatabaseName := UniqueGuid(); // Unique Name
  CoInitializeEx(nil, COINIT_MULTITHREADED);
  Result := TElevateDBConnectionAdapter.Create(Conn, true);
end;

Try setting AutoSessionName to True in TEDBSession.
