Unhandled promise rejection

[jdnichollsc]

Hi guys,

I'm trying to insert a document:

var author = { _id: '123', name: 'John Carter' };
return authorsCollection.insert(author);

But I've the following error:

(node:9632) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): TypeError: Cannot create property '_id' on string 'local.authors'

Thanks in advance, Nicholls

Hi,

I got the same error, and it works for me to use db.authors.insert instead. But I want to know whether I use it incorrectly or it's a bug. Thanks.

Isn't it a problem with your connection? Because then it would make sense that the collection object isn't created. If you have:

const db = mongo('mongodb://RemoteConnectionString');
const authorsCollection = db.collection('authors');

and the connection to the remote server fails, the authorsCollection object isn't initialized.

Does db.authors.insert work all the way up to inserting in the db? Or does it throw another error?

[ChJJin]

No, the collection has been created before. And db.authors.insert works after that without throwing another error.

Hi, Same things for me and I just want to know why

db.authors.insert

and not

authorsCollection.insert(author);

It's a spec update?
