BUG: Argument #1 ($src) must be of type string

[DanYouCan]

I have upgraded TYPO3 from version 9 (vhs V6.1.3) to 12 vhs V7.0.3. With V12 I got the following error:

FluidTYPO3\Vhs\ViewHelpers\Media\ImageViewHelper::getImgResource(): Argument #1 ($src) must be of type string, TYPO3\CMS\Core\Resource\FileReference given, called in /html/typo3-upgr/typo3conf/ext/vhs/Classes/Traits/SourceSetViewHelperTrait.php on line 48

For that my frontend fluid code was (it was taken over from V9):

<v:media.image
  src="{file}"
  width="{dimensions.width}"
  height="{dimensions.height}"
  alt="{file.alternative}"
  title="{file.title}"
  class="image-embed-item"
  treatIdAsReference="true"
  srcset="576,768,992,1200,1900"
  srcsetDefault="768"
  additionalAttributes = "{loading : 'lazy'}"
  quality="75"
/>

After debugging and trial I ended up with following working code:

<v:media.image
  src="/fileadmin/{file.originalFile.identifier}"
  width="{dimensions.width}"
  height="{dimensions.height}"
  alt="{file.alternative}"
  title="{file.title}"
  class="image-embed-item"
  treatIdAsReference="true"
  srcset="576,768,992,1200,1900"
  srcsetDefault="768"
  additionalAttributes = "{loading : 'lazy'}"
  quality="75"
/>

So it looks like this view helper in vhs V7.0.3 can no longer handle objects like {file}? Is this intentional? Thank you in advance for checking my statement.
