Crashes with TypeError: OCA\FaceRecognition\Helper\Euclidean::distance(): Argument #1 ($vector1) must be of type array, string given, called in

[wojciechczyz]

Hey, Thanks for reporting issues back to Nextcloud Face Recognition. Please, try to complete this report in detail so we can help you easier. :smile:

Make sure you read all the documentation, and the FAQ, and that the issue has not been reported before. :wink:

Expected behaviour

when running:

php occ face:background_job --cluster-mode

It starts clustering and then crashes: 1/3 - Executing task CheckRequirementsTask (Check all requirements) 2/3 - Executing task CheckCronTask (Check that service is started from either cron or from command) 3/3 - Executing task CreateClustersTask (Create new persons or update existing persons) Face clustering will be created for the first time. There are 47 faces for clustering An unhandled exception has been thrown:
