error object not properly formatted

[jcferrer]

On a db.get with an invalid doc Id, the error returned is not properly formatted.

couch.db.get(id, { revs_info: true }, function(err, body) {
    if (err) { 
         debug(err);
    ......
    ......
  });

The error object looks like this:

{ [Error: missing]
  name: 'Error',
  error: 'not_found',
  reason: 'missing',
  scope: 'couch',
  statusCode: 404,
  request:
   { method: 'GET',
     headers:
      { 'content-type': 'application/json',
        accept: 'application/json' },
     uri: 'http://couchhost:5984/db/tsp2',
     qs: { revs_info: true } },
  headers:
   { date: 'Thu, 17 Mar 2016 19:23:40 GMT',
     'content-type': 'application/json',
     'cache-control': 'must-revalidate',
     statusCode: 404,
     uri: 'http://couchhost:5984/db/tsp2' },
  errid: 'non_200',
  description: 'couch returned 404' }

I saw in one of the examples references to the error object like the following, where the error object seems to have a message and a 'status-code' property:

  db.get('foo', function (error, body, headers) {
      if(error) { return response.send(error.message, error['status-code']); }

Please advise.

I get the same malformed error messages (here is example of attempting to create database that exists):

nano.db.create('testdb', function(err, body) {
  if (err) {
    console.log(err);
  }
});

 { [Error: The database could not be created, the file already exists.]
  name: 'Error',
  error: 'file_exists',
  reason: 'The database could not be created, the file already exists.',
  scope: 'couch',
  statusCode: 412,
  request: 
   { method: 'PUT',
     headers: 
      { 'content-type': 'application/json',
        accept: 'application/json' },
     uri: 'http://localhost:5984/testdb' },
  headers: 
   { date: 'Thu, 28 Apr 2016 17:04:59 GMT',
     'content-type': 'application/json',
     'cache-control': 'must-revalidate',
     statusCode: 412,
     uri: 'http://localhost:5984/testdb' },
  errid: 'non_200',
  description: 'couch returned 412' }

When done with curl: curl -X PUT http://localhost:5984/testdb | json_pp:

{
   "error" : "file_exists",
   "reason" : "The database could not be created, the file already exists."
}

It seems this is a console.log and/or NodeJS thing (I'm new, sorry!). console.log(err.toString()) formats it properly, though I'm still not sure why the error message came out so awkwardly before.

Hi @jcferrer and @cboden, my impression is that the nano documentation is out of date. The 'status-code' property no longer exists, and it has been replaced by 'statusCode'. I filed issue #328 for this.

Regarding the 'message' propery, I think that property is output like [Error: ] by Node.js, so nano is ok there.

I see this issue was filed a couple months ago, so you've likely moved on, but does this reply address your question?

It seems that this question has been answered, if so could you close this issue?
