Commands Run

$ echo "apiVersion: 1
output: HelloWorld
tasks:
  HelloWorld:
    run: noop
    inputs: Hello, world" > hello-world.1.wf.yaml
$ echo "apiVersion: 1
output: HelloJon
tasks:
  HelloJon:
    run: noop
    inputs: Hello, Jon" > hello-world.2.wf.yaml
$ fission fn create --name hello-world --env workflow --src ./hello-world.1.wf.yaml
$ fission fn test --name hello-world
Hello, world
$ fission fn update --name hello-world --env workflow --src ./hello-world.2.wf.yaml
$ fission fn test --name hello-world
Hello, world

Expected Output

The last command should have output Hello, Jon corresponding to the workflow from the update command, but it instead has the workflow from the original workflow function creation command.

Other Notes

If you do a fission pkg info with the name of the package for the function it will display the updated function, however if you do a fission-workflows wf get on the workflow it seems to show the original workflow.
