[info stacktrace] → ask for assistance

Hi,
my goal is to transfer the "errorInfo" into a "stacktrace" used by my SW.
-> I require: command, fileName and lineNumber
-> the [info errorstack] return "something" which is missing some essential parts.
[info errorstack]:
 > INNER {invokeStk1 ::tcllcconfig::LcSettingC::MK_NULL LookupBool in} CALL {::oo::Obj40::my LcSettingLookupBool}
as I understand:
$setting LookupBool $name == ::tcllcconfig::LcSettingC::MK_NULL LookupBool in
-> problem: post versa pre parse expression
-> problem: the fileName(class etc) is *not* available
==== lcconfig-2-0-5-(0-0-0+binary+pipe+tcl.pipe.pipe) use invalid cfs FAILED
