A LogicalSessionCacheRefresh is triggering a failpoint configured in driver's retryable reads tests.
Here's a log of the failpoint being configured:
2019-08-28T23:50:02.549+0000 W COMMAND [conn770] failpoint: failCommand set to: { mode: 3, data: { failCommands: [ "find" ], errorCode: 91 } } 2019-08-28T23:50:02.549+0000 I COMMAND [conn770] command admin.$cmd command: configureFailPoint { configureFailPoint: "failCommand", mode: { times: 1 }, data: { failCommands: [ "find" ], errorCode: 91 }, $db: "admin", $clusterTime: { clusterTime: Timestamp(1567036202, 335), signature: { hash: BinData(0, 57D9AC22A95A2C0F6B3FC988600F0EBDAE1A3\ 98B), keyId: 6730367942157926402 } }, lsid: { id: UUID("bbcf418f-9ebf-4399-815e-063007855163") } } numYields:0 reslen:163 locks:{} protocol:op_msg 0ms
And here's a log of the failpoint being triggered:

Driver tests expect that, by default, internal commands like this do not trigger failpoints.
This is a significant bug for drivers because tests fail in apparently random fashion based on the timing of the background processes running in the server, resulting in difficult to debug test failures.
