Cannot assign array to property In2code\In2studyfinder\Hooks\PluginPreview::$templatePathAndFile of type string

[klodeckl]

If the typoscript template of in2studyfinder is not included (e.g. because multisite installation and in2studyfinder is not needed on every site) the following error occurs:

Cannot assign array to property In2code\In2studyfinder\Hooks\PluginPreview::$templatePathAndFile of type string

Including the static typoscript template helps.

in2studyfinder 9.0.4 and TYPO3 11.
