Can't resolve custom external type if it's not array

Hello,

I might be missing something, or there seems to be an issue with soul command-line tool resolving externals of custom type that are not arrays.

I have a custom struct Wave that holds a single member of type soul::audio_samples::Stereo called audioData and I’m trying to get it from external source:

…it works perfectly fine with the array, but for some reason soul command-line tool can’t resolve external for the singleWave
