Validation does not work with own extension

[JeppeDonslund]

Describe the bug
When implementing jh_captcha in my own extension, I get this error: Validation failed while trying to call ...erController->showAction().

Affected versions

• TYPO3: 10.4
• jh_captcha: 4.0.0
  My own extension

If I remove "Validate" from the model, it works, but the captcha is obviously not validated.

Sorry, the "Developer Corner" section in the documentation is outdated. The function has not been tested for a long time. Since I don't have a need for it myself at the moment, I don't expect a fix. You are welcome to create a pull request.
