I'm using TYPO3 9.5.3 and the sf_books extension to manage books.

I inserted book on BE with image cover for the book item.

I get this error on the singleView (detail) :

The argument "image" was registered with type "object", but is of type "string" in view helper "TYPO3\CMS\Fluid\ViewHelpers\ImageViewHelper".

When I check the template file I find this code supposed displays an image :

<f:image image="{book.cover}" maxWidth="200" alt="{book.title}"/>

How can I change this code the solve the error and display the cover book ?

good stuff

  • Thanks, I used it, but i get this error `The argument "each" was registered with type "array", but is of type "string" in view helper "TYPO3Fluid\Fluid\ViewHelpers\ForViewHelper".` – good stuff Aug 29 '19 at 12:42
  • Without the context i cant help you. what exact version of the extension? What template folder and file is it? What field? Where is the file stored(in sf_books or your sitepackage)? This problem should be solved in version 5.2.2 – Sebastian Fischer Aug 30 '19 at 14:30
