occ fulltextsearch:index throws exception: OCA\Files_FullTextSearch\Service\ExternalFilesService::getExternalMountById() must be of the type integer, null given

Hi,

I run Nextcloud 16.0.4 with Fulltextsearch 1.3.6. When executing occ fulltextsearch:index for the first time to build an index, I fail with index completion as an exception is thrown during building the index.

This is the last output from building the index:

From this state, occ fulltextsearch:index stopped execution:

Start with apps/files_fulltextsearch/lib/Service/ExternalFilesService.php at lines 244 and 258, then trace the caller chain through FilesService.php. Reproduce with occ fulltextsearch:index using the reported Nextcloud and Fulltextsearch versions and inspect the external mount value for the failing folder. Done means indexing no longer terminates with the reported TypeError.
