I'm not sure how portable this `awk` line is, but in any case, I don't think it's needed, if all you're trying to do is to set a specific string for different cases. You can use yaml2obj's -D option to specify a specific value that replaces `[[VARNAME]]` in the fields. The variable can even have a default value. Finally, with a bit of additional work in yaml2obj, you can specify something like `[[VARNAME=<none>]]` and yaml2obj will treat the field as not being present at all (see ELF for some examples of all of the above).
