Node.js app crashes when creating indexes for mongodb

Question

When i creating indexes via createIndex or ensureIndex methods my node.js app crashing without providing any details of occured error.

Also i have noticed that all my code works very well with my localhost mongodb until i use remote mongdb atlas replica set.

Node.js: 8.5.0 Mongodb: 3.6.4 Mongodb driver for Node.js: 3.0.8

Example code (but i have tried different variants of implementation, nothing helps):

db.collection('stars').ensureIndex({name: 1}, { unique: true });

I am already listening for uncaughtException and unhandledRejection events, but they dont fire on this crash.

What can i do to get details or get rid of this error?

Thanks for any help!

Answer 1

I updated my mongodb driver to version 3.1.0 and eventually got error message with description of reason that causes the problem. According to error message: "The field "retryWrites" is not valid for for an index specification". So, i think the problem was with this field that i used to add to my connection uri string. After removing this field i got rid of this problem.

Answer 2

The problem might be connected with this issue: NODE-1641. I've got similar problem and found a few solutions:

• Locking driver version at 3.1.0 and adding useNewUrlParser: true in connection options.
• In createIndex add field retryWrites: null, so in your case it will look like: db.collection('stars').ensureIndex({name: 1}, { unique: true, retryWrites: null });

However you need to check if it won't turn off retryable writes for that collection.

• Last option is to vote up that issue and hope that it will be resolved soon, and then update your driver.
