In the expression evaluator:

a = {x = 1} {x = 1} a.get("\"x")

yields: "Failed to evaluate expression null"

Hitting "Dismiss" and continuing by hitting will keep giving the same exception.

Stacktrace:

This was solved in the slipstream of addressing another issue, see: https://projects.ecoinformatics.org/ecoinfo/issues/5722

The same problem reappeared, needs looking into.

Fixed.

x = {a = 1} {a = 1} x.get("b") No such key: "b"
