Mongorestore of oplog collection fails if it includes view creation

[Akshaya_Srinivasan]

Hi,

I periodically take dump of the oplog collection and during restore I apply it using mongorestore utility.
If I have a view creation, which is captured by oplog backup and if I try to restore it, it fails with below error.
Please can someone help to resolve it and restore views.

Hi @Akshaya_Srinivasan,

Which versions of mongod and mongorestore are you running?

https://jira.mongodb.org/browse/SERVER-47469

It looks like this has been fixed in 4.2.10, 4.4.2 and 4.7.0 (dev version, future 5.0 I think).

Thanks,
Maxime.

I am using 4.2.8 version mongod and mongorestore. Will try with 4.2.10 and update.
