Hi all - do you know if there is any way to test with

materialize_to_memory

when the top upstream asset is a

SourceAsset

? The source asset is just a static file, and I have an io manager for loading said asset. I think it's currently failing due to the io manager getting overridden by

materialize_to_memory

? I don't know if there is a better way of defining it; defining it like a normal asset just seems to go against the idea of separating generation and I/O, i.e. I wouldn't be able to swap file system as easily.
