I found an error when trying to use Mongodb's queryable encryption

I tried to use the queryable encryption function of MongoDB according to the official documents(Quick Start of Queryable Encryption), and copied the Complete Python Application example to run on my local computer.However, an error occurred during the compilation of the make_data_key.py.

The error message is as follows:

Traceback (most recent call last):
  File "D:\Python\project\MongoDBtest\make_data_key.py", line 119, in <module>

I wonder how to solve it.

The previous problem has been solved, and now a new problem has been discovered.

The error message is as follows:

I have the exact same error, have you figured out a solution to the problem yet?

Hello yuhan_cai (and Nicklas_Wurtz) and welcome to the Community!

Queryable Encryption is not supported on standalones so you have to use either a replica set or sharded clusters, but it sounds like you got that part solved. The error you are seeing seems like it is coming from a server version that does not support clusteredIndex. What server version are you using?

Thank you Cynthia_Braund!

I am using an Atlas Cluster

I’ve read a bit more about Queryable Encryption on MongoDB and figured out that since I’m using the free version which unly supports version 5.0 of MongoDB, I will not be able to use Queryable Encryption. It seems that the only supported version of MongoDB which can use the feature is 6.0+.

It might be related to the error we are encounting, but I’m not sure
