GCS storage from server running on Google Cloud VM.

[gincessant]

I have a pecular issue with uploading files to GCS. I am able to upload files to GCS using the command manually. But when sftpgo is started using Systemctl I always get Error Uploading Files. I have tried many overrides and sftpgo.json changes, specifically, adding a temp_path and override.conf with commands like these (a few at a time not all together) like this:

--- To make sure I am using my sftpgo.json file with temp_path set to /var/lib/sftpgo/tmp

[Service]
ExecStart=
ExecStart=/usr/bin/sftpgo serve --config-file /etc/sftpgo/sftpgo.json

--- Try to have sftpgo use a special environment

WorkingDirectory=/run/sftpgo
Environment="SFTPGO_COMMON_TEMP_PATH=/run/sftpgo"
RuntimeDirectory=sftpgo
RuntimeDirectoryMode=0700

--- Make sure it is really running as sftpgo. -- it is

User=sftpgo
Group=sftpgo

--- TEMPORARY TEST --- This was true

ProtectSystem=no

--- TEMPORARY TEST --- I added this

ReadWritePaths=/

Nothing seems to work. Always I get this error which looks to me that systemctl sftpgo is trying to create a pipefile in the root.

I did find another issue with this error but there was no solution given just marked as Support Request.

Any ideas?
Thanks in advance.
