Error: ENOENT with Bunyan spin file registration (NodeJS)

Question

I am using the Bunyan module for NodeJS logging. When I try to use a rotating file type, it crashes my application every time and outputs this error:

Error: ENOENT, rename 'logs / info.log.3'

However, this never happens at the same time, so I can’t find any logic ... Here is how I manage my registrar:

var log = Bunyan.createLogger(config.log.config);
log.info('App started, ' + process.env.NODE_ENV);

And here is my config.json:

  {
    "name"    : "app",
    "streams" : [
        {
            "type"  : "rotating-file",
            "period": "5000ms",        //Low period is for testing purposes
            "count" : 12,
            "level" : "info",
            "path"  : "logs/info.log"
        },
        {
            "type"  : "rotating-file",
            "period": "5000ms",
            "count" : 12,
            "level" : "error",
            "path"  : "logs/error.log"
        },
        {
            "type"  : "rotating-file",
            "period": "5000ms",
            "count" : 12,
            "level" : "trace",
            "path"  : "logs/trace.log"
        }
    ]
  }

Can anyone advise how to fix my problem? Thanks in advance.
