      If no jstest ran before it, the database test will not exist when explain_missing_collection.js is run, since a previous test will not have created the database as a part of creating some other collection. This will cause the explain to fail:

      [js_test:explain_missing_collection] Implicit session: session { "id" : UUID("4a1e56e2-7511-433a-a11b-81fc6009e44e") }

      You can use this suite to reproduce the problem:

      test_kind: js_test

selector:
  roots:
  - jstests/core/explain_missing_collection.js

executor:
  fixture:
    class: ShardedClusterFixture
    mongod_options:
      set_parameters:
        enableTestCommands: 1
    mongos_options:
      set_parameters:
        enableTestCommands: 1
    num_shards: 1
    num_rs_nodes_per_shard: 1

      I don't know if this is a problem with the test or mongos so I'm deferring that to the Sharding Team.
