In real circumstance, if jcheck configuration file is missing, we will get `UncheckedRestException` with status code 404  from GitHub or GitLab. However, if the jcheck configuration file is missing in local environment, we won't get `UncheckedRestException` , instead, we will only get `NoSuchElementException`. If we don't catch this exception here, the test will not be able to continue.
