      Since viewless timeseries collection have an UUID, it should be possible to insert to it specifying the collectionUUID parameter on the insert command line this:

      db.runCommand({
    "insert": "ts",
    "documents": [{ "t": ISODate() }],
    "collectionUUID": UUID("a1b2c3d4-e5f6-7890-1234-567890abcdef")
});

       

      However, currently this fails with a CollectionUUIDMismatch error with expectedCollection being the same as actualCollection:

      {
    "ok" : 0,
    "errmsg" : "time-series insert failed: test.ts :: caused by :: Collection UUID does not match that specified",
    "code" : 361,
    "codeName" : "CollectionUUIDMismatch",
    "db" : "test",
    "collectionUUID" : UUID("a1b2c3d4-e5f6-7890-1234-567890abcdef"),
    "expectedCollection" : "ts",
    "actualCollection" : "ts"
}

      This case should be tested by the timeseries_collection_uuid.js test.
