5.  Enter logical database

Hi Karen,

i recommend you guys opening a support case with OutSystems tecnichal support for detailed troubleshoot and analysis. And if you can share the solution/workaround you'll get (or already have) it would be great as it could be very usefull to others.



I'm having this same error. Did you find what the problem was and the solution?
