Hi @Jonathan Farmer - If you're still hitting this issue, could you try again? I tested again and the same condition worked for me as expected :
The following input evaluates to False:
{
"a":2,
"b":3,
"c":5
}
The first value (of "a") is not 1 and it evaluates to False likely because "b" and "c" are also being tested against their values.
