Remove null values from stdout in ansible

Can someone let me know how to remove null values from stdout_lines.
Output

"stdout_lines": [
        "",
        "D:\\Program Files\\Apache Softwarecoder.exe",
        "",
        "D:\\Program Files\\Apache Software\\cat8.5.exe",
        "",
        "",
        ""
    ]

Expected Output

"stdout_lines": [
        "D:\\Program Files\\Apache Softwarecoder.exe",
        "D:\\Program Files\\Apache Software\\cat8.5.exe"

    ]

I tried as below

path: "{{test.stdout_lines | rejectattr('') }}"
path: "{{test.stdout_lines | reject('')|list }}"
path: "{{test.stdout_lines | rejectattr('')|list }}"

But I Get error as below or no change in output:

"path": "<generator object _select_or_reject at 0x7fb349f45cd0>"

reject does the job

    path: "{{ stdout_lines|reject('match', '^$')|list }}"

as well as select

    path: "{{ stdout_lines|select('match', '.+')|list }}"
