S3 Gatway ERROR Unable to split host port invalid port number

[centminmod]

Hi new to JuiceFS using latest beta. I set up JuiceFS local sqlite + Cloudflare R2 S3 object storage as outlined in my write up at https://github.com/centminmod/centminmod-juicefs and all was working fine.

I set up the S3 Gateway as a systemd service file https://github.com/centminmod/centminmod-juicefs#systemd-service-starting-juicefs-s3-gateway and that worked but after a while, the service wouldn't start up and even manually starting S3 Gateway would get the error ERROR Unable to split host port sqlite3://myjuicefs.db: invalid port number (see below) ??

Any ideas where the problem is?

juicefs -V
juicefs version 1.0.0-beta3+2022-05-05.0fb9155

cat /etc/redhat-release 
CentOS Linux release 7.9.2009 (Core)

and get error

Ah looks like my problem was

--writeback true \

should be

--writeback \
