Help setting up rclone.plist on macos Sierra

I have rclone synching with gdrive just fine via .sh execution, but I’d like to automate. cron is being slowly neglected by Apple, so I created the following com.github.ncw.rclone.plist in /Library/LaunchDaemons. Sucker is seen, but does not execute. Here is the plist contents

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "">
<plist version="1.0">

Execution ends with this line in console

Dec 27 13:30:11 borg[1] (com.github.ncw.rclone[43708]): Service could not initialize: 16D17a: xpcproxy + 11765 [1475][286733C4-18D9-396D-B01B-A096BE5B1DC1]: 0x2

Any help pointing out my mistake or possible reasons would be appreciated.

That isn’t a wildly helpful log message is it!

Are there any other logs available? Can you execute automate with debug or something like that?
