Today I went to change some code from a series of structKeyExists() calls to using safe navigation, for example:
structKeyExists( response, 'data' ) && structKeyExists( response.data 'status' ) && structKeyExists( response.data.status, 'code' )
to:
isNull( response?.data?.status?.code )
and I’m getting a low-level Java error:

Verified this is an issue with Lucee 5 on trycf.com - this is not an issue in Lucee 6. Test code below:
<cfscript>
testa = {
bob = {
jane = "here"
}
};
testb = {
bob = {}
};
testc = {};
testanull = isNull( testa?.bob?.jane );
//writeDump( isNull( testa?.bob?.jane ) );
//writeDump( isNull( testb?.bob?.jane ) );
//writeDump( isNull( testc?.bob?.jane ) );
</cfscript>
At first I thought it was just the use of isNull(), but assignment of a variable throws the same general error. Comment out the testanull variable assignment and uncomment any isNull() to see the same error thrown when using isNull() with the safe navigation.
Can anybody else confirm, please?
