Hi everyone, I tried to install traider.io in my local machine and I also met this error:

Error: Error setting TTL index on collection : sessions
...

After searched, as I know because the version of connect-mongo & mongodb is not compatible. So, in my case, I re-installed mongodb with this version & it works:

npm install mongodb@1.4.x

Hope this help for someone like me 😃
