PHP Fatal error: Trait method get has not been applied, because there are collisions with other trait methods

[silenx]

Hello, i just upgraded files_fulltextsearch to 20.0.3 on NC 20.0.9
I got a 500 error, this one:
{"reqId":"5D4H9KN7q7RS3tKTW8kV","level":3,"time":"2021-05-15T23:34:48+02:00","remoteAddr":"X.X.X.X","user":"B59EB1C5-1D23-4753-8551-D724DCA077E0","app":"PHP","method":"GET","url":"/apps/files/","message":"Trait method get has not been applied, because there are collisions with other trait methods on OCA\\Files_FullTextSearch\\Service\\ExternalFilesService at /var/www/nextcloud/apps/files_fulltextsearch/lib/Service/ExternalFilesService.php#63","userAgent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/90.0.4430.212 Safari/537.36","version":"20.0.9.1"}

Disabling plugin make NC 20.0.9 working again

Regards

EDIT:
I forgot php version:

Same issue. Maybe php version is relevant:

With NC 20.0.10 and PHP 7.2.34 having the same issue with this app. Disabled and then removed the app to cure the problem. The offending app is thankfully logged in the Method path OCA\ Files_FullTextSearch \Service\ExternalFilesService

Had exactly the same error message with all file uploads and deletions in NGINX error.log:
