On a given datasource already present & active, try to activate it or deactivate it. An error window pops up with message : "Incorrect result size: expected 1, actual 0" the attached file shows a part of file stdout logfile. error_message_activate.txt When it appears, the datasource state is not toggled. After some page refresh, it may finally succeed.

Hi @nduvernois,

This is because the database events have been removed. In version 2.8.0 this error will no longer occur here, because in this version we do not retrieve the event from the database this place. However, it is worth securing the service that retrieves the events, in such a case, this will also be corrected in version 2.8.0.

Regards.
