If `SOLVEBIO_API_KEY` is `None`, then this code should not execute. I have your PR running locally and don't have the api key set. When the key is not set, the results table doesn't render because each of the `api/samples/variants/<id>/` calls fail with the following error. While we would expect this error since the key isn't set, it would be better if there is no call made to solvevio resources when the `SOLVEBIO_API_KEY` setting is not valid.

Sorry, your API credentials seem to be invalid.
