You have a section mismatch because your code evidently doesn't live in
an init section, but is trying to access data which does. The fact that
the data happens to be a list of compatible strings is irrelevant, and
this is in no way related to dt.

Figure out whether your function should live in an init section or if
the data should not. Make sure that you don't reference anything in init
section from anything else which does not itself live in an init
section. That will solve your build issue.

The name of the function sounds suspicious to begin with from a DT
perspective. You shouldn't need to override DT properties from the
command line.

Thanks,
Mark.
