Hi,

I'm running cutadapt (from TS) on a collection with 96 datasets, started from a workflow as an intermediate step. About half of them fail with this message.

Traceback (most recent call last): File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/runners/__init__.py", line 590, in finish_job job_state.job_wrapper.finish( stdout, stderr, exit_code ) File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/__init__.py", line 1261, in finish ActionBox.execute(self.app, self.sa_session, pja.post_job_action, job) File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/actions/post.py", line 532, in execute ActionBox.actions[pja.action_type].execute(app, sa_session, pja, job, replacement_dict) File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/actions/post.py", line 405, in execute for input_dataset in [x.dataset for x in j2c.input_datasets if x.dataset.creating_job.workflow_invocation_step and x.dataset.creating_job.workflow_invocation_step.workflow_invocation == wfi]: AttributeError: 'NoneType' object has no attribute 'input_datasets'

Running release 15.07 rev cf29f6c4a7 Is that Known? How to avoid?

Best, Alexander
