Need error reporting that doesn't dump entire script into my log

[XLTechie]

Currently, I am having an issue wherein invoking the action as follows:

      - name: Create installer
      uses: joncloud/makensis-action@v5.0

Is resulting in the following difficult to parse error text being dumped into my job log:

##[group]Run joncloud/makensis-action@v5.0
with:
  script-file: install.nsi
env:
  pythonLocation: C:\hostedtoolcache\windows\Python\3.13.11\x64
  PKG_CONFIG_PATH: C:\hostedtoolcache\windows\Python\3.13.11\x64/lib/pkgconfig
  Python_ROOT_DIR: C:\hostedtoolcache\windows\Python\3.13.11\x64
  Python2_ROOT_DIR: C:\hostedtoolcache\windows\Python\3.13.11\x64
  Python3_ROOT_DIR: C:\hostedtoolcache\windows\Python\3.13.11\x64

If this output is in your control (I've never written an action, but having seen some fail, it's usually prettier than that), please consider making this into a simple one-line error message or the like.

For what it's worth, the underlying difficulty here is issue #39, though the 5,000 plus character error report doesn't lend itself to clear parsing.
In part because I use a screen reader, and so can't as easily find the visually relevant part of the text, and initially had to read through this a couple times to find where the actual error was. But even so, dumping the entire script back as a log entry is just irregular.
