Generate_and_run endpoint fails at loss generation

[sambles]

Issue Description

When calling generate and run the output stage of generate-oasis-files is not correctly linked to the input of generate-losses

See this func from the Platform 1 version of the code before it was scrapped for Platform 2, somthing must have broken when porting the change over to the newer verison.
