      Description

      Somewhere between v4.1.7-51-gb4f82034e6 and v4.1.8-73-ge2251dbc97, tests for the convenient transactions API started failing because the server ceased to return a code and code name for DuplicateKey errors.

      The test: https://github.com/mongodb/mongo-ruby-driver/blob/master/spec/spec_tests/data/transactions_api/callback-retry.yml#L129

      The response we are currently getting with 4.1.8:

      {"n"=>0, "writeErrors"=>[{"index"=>0, "code"=>11000, "keyPattern"=>{"_id"=>1}, "keyValue"=>{""=>1}, "errmsg"=>"E11000 duplicate key error collection: ruby-driver.test index: _id_ dup key: { _id: 1 }"}], "opTime"=>{"ts"=>#<BSON::Timestamp:0x000055dd583c1488 @seconds=1550719073, @increment=3>, "t"=>2}, "electionId"=>BSON::ObjectId('7fffffff0000000000000002'), "ok"=>1.0, "$clusterTime"=>{"clusterTime"=>#<BSON::Timestamp:0x000055dd583c0e70 @seconds=1550719073, @increment=3>, "signature"=>{"hash"=><BSON::Binary:0x47204578231900 type=generic data=0x0000000000000000...>, "keyId"=>0}}, "operationTime"=>#<BSON::Timestamp:0x000055dd583c0bc8 @seconds=1550719073, @increment=3>}
      

      It includes errmsg but no code or code name.

      4.0 response for comparison:

      {"operationTime"=>#<BSON::Timestamp:0x00005620520854f8 @seconds=1550719590, @increment=3>, "ok"=>0.0, "errmsg"=>"E11000 duplicate key error collection: ruby-driver.test index: _id_ dup key: { : 1 }", "code"=>11000, "codeName"=>"DuplicateKey", "$clusterTime"=>{"clusterTime"=>#<BSON::Timestamp:0x000056205209c680 @seconds=1550719590, @increment=3>, "signature"=>{"hash"=><BSON::Binary:0x47348407684780 type=generic data=0x0000000000000000...>, "keyId"=>0}}}
      

      It looks like previously DuplicateKey was returned as a top level error, and then it had code name and code, and now DuplicateKey is a write error and it does not have code name and code anymore.
