Before issues find out slove：as a workaround, you can use a newer version of goharbor/prepare:v2.3.0-rc1. Or you can wait for the stable release like goharbor/prepare:2.2.3 or goharbor/prepare:2.3.0

The same error is reported.

Hi @lklkxcxc , Could you provide the 1.10 yaml you are using? and btw we don't have version 2.10.0, are you migrate to 2.1.0 official release or which exact version it is?

[lklkxcxc]

@MinerYang Sorry ! It release is 2.1.0. yaml content:

external_redis:
  host: 192.168.1.146
  port: 6379
