Hello Mark, thank you for your advice. I figured out what I did wrong now. And my function has "bt" in its name and not "dt". So, don't worry, I don't mess with the DT there.

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.
