we found an issue on an expression tag whenupgrading from Ignition 7.9 to 8.0.12: our tag check the connection on a linked DB using the expression isDBConnectionAvailable, this formula was working in 7.9 but not in 8.0.
The Diagnostic of the tag says “Unknown function: isDBConnectionAvailable”, even if we try to retrieve the DB name by Tag, with apex or putting the DB name in parenthesis. To avoid syntax errors, i tried to copy the function using the tooltip, but that didn’t work too
I’m attaching screenshots of the error and of our configuration, the tag
Thanks a lot for every reply
