Unable to find certificate: "" and is not set.

[NeckBozia]

Steps to reproduce

docker中运行acme，SYNO_Certificate参数设置为”“，定时运行脚本

bash /volume1/docker/Acme/cert-up-docker.sh >>/volume1/docker/Acme/log.txt 2>&1

更新证书时报错 Unable to find certificate: "" and is not set.
此报错可稳定复现且未作任何配置改动

Please upgrade to the latest code and try again first. Maybe it's already fixed. acme.sh --upgrade If it's still not working, please provide the log with --debug 2, otherwise, nobody can help you.

I have the same issue with the latest image version(20240430)
If set SYNO_Create=my domain, cer can be deployed with a new one instead of renew.
加了这个变量后能上传，但是会新建一个，而不是替换原来的
