SFTP and readlink : invalid argument

[dani]

When accessing SFTPGo using the SFTP protocol, I have tons of debug/error lines like this

{"level":"error","time":"2025-02-20T14:48:11.575","sender":"SFTP","connection_id":"SFTP_69c8ca3600d7d4b6fc846327bdc7e90d371cf17b9ee794005498a9d4f29cb4c3_1","message":"generic path error: readlink /data/share/TEST: invalid argument"}

it's not the case when using the FTP protocol. Any idea where it can come from and how to silent them ?
