How to pass temporary file name as command line argument?

[robertmircea]

I am trying to perform the following scenario:

• read entire payload
• save the payload to disk in a temporary file
• execute a command with temporary file name as argument

How can I pass the temporary file name as command line argument for the command to execute? I've reached this stage, but it doesn't work. Ideally I would not like to use a shell script, but call jq directly.

---
- id: "echo"
  execute-command: "jq"
  command-working-directory: ""
  pass-arguments-to-command:
    - source: string
      name: "."
  pass-file-to-command:
    - source: entire-payload
      name: payload

and the output:

There's currently no way to do what you want without a shell script. pass-file-to-command only provides the filename as an environment variable, and webhook doesn't provide a means of passing that value to pass-arguments-to-command.
