How to set columns config in forever

I am using forever npm module for to run scripts forever. I was trying to change columns order on list command using

forever set columns ['uid','command','dir','script','forever','pid','id','logfile','uptime']

But forever takes value as string type instead of array type:

info:    Setting forever config: columns
data:    {
data:      root: '/root/.forever',
data:      pidPath: '/root/.forever/pids',
data:      sockPath: '/root/.forever/sock',
data:      loglength: 100,
data:      logstream: false,
data:      columns: '[uid,command,dir,script,forever,pid,id,logfile,uptime]' <--- String type
data:    }

Hence on running list command now, I am getting this error:

/usr/local/lib/node_modules/forever/lib/forever.js:791
    return [prefix].concat(columns.map(mapFn));

There are couple of things I need help about:

• How to undo this?
• How to change column order?
