Error 500 in image_captcha image

I've created this patch to fix it, works for me.

Thanks for the report. Sorry, but the reason isn't really clear to me at the moment, and nobody reported this before. So we should find out, if this might be a project-specific configuration error or a general issue.

Your fix looks like a workaround, as

$font = $fonts[array_rand($fonts)];

should always return only one item. Why does it return more than one for you? Any ideas?

I'm encountering the same issue.

Yes,
$font = $fonts[array_rand($fonts)];
returns only one.

But
$font = _image_captcha_get_font_uri($font);
doesn't.

It returns an array of all fonts available, because in _image_captcha_get_font_uri it expects a token, but a font path is provided.

The fix works, even on 1.x, but is probably not the correct solution.

Also getting this error.

Attached a new temporary patch for latest version.

@corneboele any difference to #2

Could someone prepare this as MR please?

@Anybody just that it applies to 1.12/2.x latest. But the patch is imo not the right solution, see #4. I think we need to fix that not a font path is given to `_image_captcha_get_font_uri`, but a token.

as of #10

I'm facing the same issue after I did a composer update today, for #04 🐛 Error 500 in image_captcha image Closed: cannot reproduce , the param is already a token I confirm (key value of the $fonts).

Just the $fonts recieved on param at captcha/modules/image_captcha/src/Service/ImageCaptchaRenderService.php:293, are not the same $available_fonts returned by _image_captcha_get_available_fonts_from_directories() on web/modules/contrib/captcha/modules/image_captcha/image_captcha.module:54. the list is different, which cause the token to not be found.

ok found it I think $fonts returned on web/modules/contrib/captcha/modules/image_captcha/src/Service/ImageCaptchaRenderService.php:97:

  public function generateImage($code) {
    $fonts = _image_captcha_get_enabled_fonts();

Are not the same as $fonts returned on web/modules/contrib/captcha/modules/image_captcha/image_captcha.module:52 :

function _image_captcha_get_font_uri($token = NULL) {
  $fonts = [
    'BUILTIN' => 'BUILTIN',
  ];
  $available_fonts = _image_captcha_get_available_fonts_from_directories();
  foreach ($available_fonts as $file_token => $font_info) {
    $fonts[$file_token] = $font_info['uri'];
  }
  return ((!empty($token) && !empty($fonts[$token])) ? $fonts[$token] : $fonts);
}

What fixed the issue for me is to do drush updb, after doing it I started to see common fonts.

Did everyone here run update.php or drush updb after the update?
Any please also run drush cr afterwards. Who still has the issue then?

Confirming that drush updb resolves the issue. I forgot to run it locally on my dev machine.

Thanks @daveiano! :)

Our deployment process runs drush deploy, which I understand runs database updates and cache rebuild. However for the sake of completeness I ran drush updb and drush cr, and we are still seeing this issue.

The suggestion from #5 of setting a font did resolve the error.

I've revisited this.
Now using drupal 10.0.11, captcha 2.0.5 and image_captcha 2.0.5 on a staging site and the error shows.
Using `drush updb` and `drush cr` does not resolve the issue.

However, now after setting a font I'm no longer seeing the error.

I was running into this error, and it resolved after I went into the module settings, selected a font, and saved. It seemed as if there weren't any selected. Not sure how it got into that state.
