(1/1) TypeError strpos(): Argument #1 ($haystack) must be of type string, TYPO3\CMS\Core\Resource\FileReference given

# Bug Report

## Prerequisites

* [NO ] Can you reproduce the problem on TYPO3 v11.5 LTS
* [NO ] Can you reproduce the problem on TYPO3 v12.4 LTS
* [NO] Did you [perform a cursory search](https://github.com/issues?q=is%3Aissue+user%3Abenjaminkott+repo%3Abenjaminkott%2Fbootstrap_package)
to see if your bug or enhancement is already reported?

## Description

On some news-items the bootstrap-package throws an error when processing a svg-image as file-reference.
Other news-entries work.
The exception occurs in EXT:/bootstrap_package/Classes/ViewHelpers/Data/ImageInfoViewHelper.php::67 (version 14.0.7)

## Steps to Reproduce

Not really reproduceable.
But: the viewhelper get a file-reference (object) instead of the file-name (string)

### Expected behavior

no exception when the viewhelper processes a simple strpos-cmd.

### Actual behavior

excpetion, see screenshot

### Screenshots


## Fix

change line 67:
from:
` if (strpos($src, $mediaName) !== false) {`
to:
`if (is_string($src) && strpos($src, $mediaName) !== false) {`
to make strpos typesafe.

## Versions

You can get this information from executing `composer show` at the command line
if your TYPO3 installation is composer based, otherwise the version number will
be shown in the extension manager.

Typo3 v11.5.32

Start in EXT:/bootstrap_package/Classes/ViewHelpers/Data/ImageInfoViewHelper.php at line 67 and inspect how the viewhelper receives the image source for SVG file references. Confirm that the strpos call handles the reported object input without throwing a TypeError; the issue's expected behavior is no exception during processing.
