So I tried casting there too:

An exception occurred while executing 'SELECT \"class\", \"entity\", \"events\" FROM \"oc_flow_operations\" WHERE to_char(\"events\") <> ? GROUP BY \"class\", \"entity\", to_char(\"events\")' with params [\"[]\"]:\n\nORA-00979: not a GROUP BY expression"

So I tried to cast in the select and group by the alias:

An exception occurred while executing 'SELECT \"class\", \"entity\", to_char(\"events\") AS \"casted_events\" FROM \"oc_flow_operations\" WHERE to_char(\"events\") <> ? GROUP BY \"class\", \"entity\", \"casted_events\"' with params [\"[]\"]:\n\nORA-00904: \"casted_events\": invalid identifier"

(╯°□°）╯︵ ┻━┻

One last try with:

SELECT \"class\", \"entity\", to_char(\"events\") FROM \"oc_flow_operations\" WHERE to_char(\"events\") <> ? GROUP BY \"class\", \"entity\", to_char(\"events\")

If that also fails the only thing I can imagine is we just dont group on oracle ¯\_(ツ)_/¯
