Arvados

I'm running a workflow (catbeds.cwl) that uses expression tool to get all the bed files from a directory, and then catting them. The workflow works fine.

But if I run the expression tool only (getbeds.cwl) https://workbench.su92l.arvadosapi.com/container_requests/su92l-xvhdp-95zyqpj0b4k1nuz, it shows the beds as an empty array.

{
    "beds": []
}

This is very confusing when we're testing the expression tool alone.
