Input variable parameters for the new Subgraph nodes seems to have an issue where they are not recognised by the graph compiler which results in a "FAILED_TO_FIND_PARAMETER" placeholder variable in Udon assembly.

In editor:

In my example I have a simple subgraph that adds 1 to an input integer and returns it. The main graph prints the value of the input before the subgraph, and the subgraphs output.

graph: https://gist.github.com/RengeMiyauchi/b96e3405e1035137ec36e7a4c4a4fae1

subgraph: https://gist.github.com/RengeMiyauchi/ebe850b3ea86043efac57fca12a1ed13

This results in the following assembly with the error "AssemblyException: Undefined data identifier 'FAILED_TO_FIND_PARAMETER'. Identifiers must be defined before use."

uasm: https://gist.github.com/RengeMiyauchi/354abd64a8f41d0207c344136b54d599

Where the input variable for the subgraph is "PUSH, FAILED_TO_FIND_PARAMETER" when it should be "PUSH, test"

modifying the uasm as such with the appropriate data_start values: https://gist.github.com/RengeMiyauchi/4321d8ccd8609e25c1ba9ca7bdf06e1d

works without issues
