BackboneError: The backbone doesn't appear to have finished DRF tests/test_emission_line/001.emission_obj.waiting

[JoshuaJoseph23]

This error occurs for me in the testing phase of the installation, after issuing the command 'make test'. Specifically, it is when py.test is run. The test_emission_line.py test fails, and the error seen in the title occurs at tests/drptestbones/backbone.py:84: BackboneError. The code leading up to the error is below:

`
def consume_queue_directory(queue_directory, test_directory=None):
"""Run the DRP until it has consumed a single queue directory.

    The DRP is run by IDL in a subprocess using the python subprocess module.

    :param str queue_directory: The path to the queue directory with DRFs which should be consumed.
    :param str test_directory: Optionally, set the root directory for test code. By default, it will be set from the relevant OSIRIS environment variable, ``OSIRIS_ROOT``.

    """
    test_directory = test_directory or os.path.join(
        os.environ["OSIRIS_ROOT"], "tests")

    if not queue_directory.endswith(os.path.sep):
        queue_directory += "/"
    if not os.path.isdir(queue_directory):
        raise IOError("The queue directory '{0}' does not exist".format(queue_directory))

I would greatly appreciate it if anyone knew of the reason for the problem and a subsequent fix!

[Tuan Do]

Is the pipeline able to run (run_odrp)?

Is there a .log file in the tests/test_emission_line directory? That would help to narrow down the problem.

Could you try checking out the 'release' branch and see if this problem remains?
