I broke this test: ``` ds_write = <datasette.app.Datasette object at 0x7f0965858700>

@pytest.mark.asyncio
async def test_insert_row(ds_write):
    token = write_token(ds_write)
    response = await ds_write.client.post(
        "/data/docs/-/insert",
        json={"row": {"title": "Test", "score": 1.2, "age": 5}},
        headers={
            "Authorization": "***".format(token),
            "Content-Type": "application/json",
        },
    )
    expected_row = {"id": 1, "title": "Test", "score": 1.2, "age": 5}

  assert response.status_code == 201

E assert 500 == 201 E + where 500 = <Response [500 Internal Server Error]>.status_code
