Problem Description
Saw error on dumping from 4.4 and master.
Steps to Reproduce
Add documents to collection, attempt to dump.
Expected Results
Successful dump
Actual Results
4.4 error: 
Failed: error writing data for collection `test.foo` to disk: error reading collection: Failed to parse: { find: "foo", skip: 0, snapshot: true, $readPreference: 
, $db: "test" }. Unrecognized field 'snapshot'.
Master was a similar error, but I didn't record it
Additional Notes
Very possible I did something wrong – I downloaded the latest version from evergreen and used that successfully, so didn't look into the original failures.
