No report generated on 0.2 with PHP 7.4

[ptmkenny]

I tried to install this via composer using the instructions in the README, but it isn't working.

composer.json

    "require-dev": {
        "emuse/behat-html-formatter": "^0.2",

behat.yml

default:
  suites:
    default:
      contexts:
        - emuse\BehatHTMLFormatter\Context\ScreenshotContext:
            screenshotDir: /app/tests/screenshots
      formatters:
        html:
          # Where to put the HTML report
          output_path: "%paths.base%"
  extensions:
    emuse\BehatHTMLFormatter\BehatHTMLFormatterExtension:
      name: html
      renderer: Twig,Behat2,Minimal
      # file_name: index
      print_args: true
      print_outp: true
      loop_break: true

behat command

/app/vendor/bin/behat /app/tests/behat/features/ -c /app/tests/behat/behat-lando.yml --tags '@testme' --clear-screenshots

Result:

Screenshots are generated properly, both by this extension and by Behat Fail Aid. But, no report is generated. I don't see an error in my test output, but there is no report, either.

So I tried adding a report option on the command line like this:

/app/vendor/bin/behat /app/tests/behat/features/ -c /app/tests/behat/behat-lando-selenium.yml --tags '@testme' --clear-screenshots --format html

This gives me the following error:

So I changed the output_path to my screenshots directory, but I am still getting the error when I try to output the report. This is strange to me because the screenshots are output correctly to the same directory, but the report has this permissions error.

How do I generate the report?

Ah, I see. I had to specify --format html --out MYDIRECTORY in the command like this:

behat /app/tests/behat/features/ -c /app/tests/behat/behat-lando-selenium.yml --tags '@testme' --format html --out /app/tests/reports`

I humbly request that you update the documentation with a new section called "behat command" so that people can more easily understand what they need to do to get this working.
