Build fails with non-constant-expression cannot be narrowed from type 'int' to 'char'

Hello
I am trying to deploy irods python rule engine for iRODS 4.2.5.
when I send make package command I get the following error:

Hi Mohamad - can you share the full path and version information for your cmake and clang?

Did you build irods/externals yourself?
If not, then why build the python rule engine plugin directly?

@mohamadhayek Any news on this?

Just making a note here that this is likely due to a missing member for some struct (see #168). I saw a similar failure that was resolved by adding a missing struct member.
