Yet it works if I change base workflow trigger to workflow_dispatch

Confirmed. I have to set inputs for the called workflow myself.

This issue is still relevant for me on act version 0.2.64.

Further debugging reveals more information.

The issue of "null input" only occurs when you trigger a workflow_call only workflow (i.e. act workflow_call -W ./my/workflow.yml), which then calls another workflow.

For the first workflow if you add on: push and run the same workflow file (i.e. act -W ./my/workflow.yml, the input is passed properly because now the "first" started workflow is not a workflow_call only one.

A decent workaround is to wrap the first workflow_call with another workflow of push or workflow_dispatch type, rather than calling it directly, emulating how it would be called by GitHub Actions.

Example for @haritowa's workflows:

# filename act_dispatch.yml
name: "My Workflow Caller"
on:
  workflow_dispatch:
jobs:
  call:
    uses: ./.github/workflows/base.yml
    with:
      name: Foo
      project: Bar
      owner: Baz
      options: FooBar
