hi
i've try to install on v8.2 an work if used as page attribute (but not with raw function).
I've try to use it on an express object but have this error
`Exception Occurred: /concrete/vendor/doctrine/dbal/lib/Doctrine/DBAL/DBALException.php:131 An exception occurred while executing 'UPDATE CantanteExpressSearchIndexAttributes SET ak_can_link = ? WHERE exEntryID = ?' with params [{"siteTree":null,"cID":"169","error":false,"pkgID":"0","cPointerID":"0","cIsActive":"1","cFilename":null,"ptID":"7","cDisplayOrder":"12","cInheritPermissionsFrom":"PARENT","cOverrideTemplatePermissions":"1","cCheckedOutUID":null,"cIsTemplate":"0","uID":"1","cPath":"/fabri-fibra","cParentID":"1","cChildren":"0","cCacheFullPageContent":"-1","cCacheFullPageContentOverrideLifetime":"0","cCacheFullPageContentLifetimeCustom":"0"}, 4]:

Object of class Concrete\Core\Page\Page could not be converted to string (0)`

any ideas for solve this problem ?
If is possible without rewrite all the code.
