Curious if there a setting for Lucee to output error messages with the variable name as it is in the code, i.e. camelCase - while “niceLocation” vs “NICELOCATION” might seem trivial enough, In one application I require many variables which kind of need to sound similar as they iterate on similar values, leading to rather long variable names (may not be ideal, but that’s beside the point here - it helps others/clients understand what is happening in the code). So when Lucee 'shouts' back [UPSSYSTEMRUNTIMEINCLUDINGAGEINGRESERVEINMINUTESONLY] doesn’t exist”, it takes my old brain a bit longer to read it than if it were to show “upsSystemRuntimeIncludingAgeingReserveInMinutesOnly”. Cheers!

could try

this setting will do the trick, downside is that code like this

serialize({susi:1})

will give a different result.
