Hi i am trying to pass the value from a field from previous stage as input to the fragment parameter . Basically I have created a fragment with shell stage and i am using this fragment in a pipeline . I want to pass the file path which i have formed by using some expressions in expression evaluator and have assigned to a field called Filename. I want to pass value from this field (“Filename”) to the fragment parameter. Can anyone suggest how to pass this .

There is an example of doing this for the shell executor in the documentation:
