Encoding profile not found

Logging a weird glitch I came across. A workflow failed due to a "missing" encoding profile, although the encoding profile "audio.wav" does indeed exist. 2018-08-23 17:57:28,397 | ERROR | pool-54-thread-1175 | (WorkflowOperationWorker:180) - Workflow operation 'operation:'compose', position:19, state:'FAILED'' failed org.opencastproject.workflow.api.WorkflowOperationException: Encoding profile 'audio.wav' was not found         at org.opencastproject.workflow.handler.composer.ComposeWorkflowOperationHandler.encode(ComposeWorkflowOperationHandler.java:217)[59:matterhorn-composer-workflowoperation:4.0.0.SNAPSHOT]         at org.opencastproject.workflow.handler.composer.ComposeWorkflowOperationHandler.start(ComposeWorkflowOperationHandler.java:132)[59:matterhorn-composer-workflowoperation:4.0.0.SNAPSHOT]         at org.opencastproject.workflow.impl.WorkflowOperationWorker.start(WorkflowOperationWorker.java:233)[183:matterhorn-workflow-service-impl:4.0.0.SNAPSHOT]         at org.opencastproject.workflow.impl.WorkflowOperationWorker.execute(WorkflowOperationWorker.java:155)[183:matterhorn-workflow-service-impl:4.0.0.SNAPSHOT]         at org.opencastproject.workflow.impl.WorkflowServiceImpl.runWorkflowOperation(WorkflowServiceImpl.java:885)[183:matterhorn-workflow-service-impl:4.0.0.SNAPSHOT]         at org.opencastproject.workflow.impl.WorkflowServiceImpl.process(WorkflowServiceImpl.java:1899)[183:matterhorn-workflow-service-impl:4.0.0.SNAPSHOT]         at org.opencastproject.workflow.impl.WorkflowServiceImpl$JobRunner.call(WorkflowServiceImpl.java:2319)[183:matterhorn-workflow-service-impl:4.0.0.SNAPSHOT]         at org.opencastproject.workflow.impl.WorkflowServiceImpl$JobRunner.call(WorkflowServiceImpl.java:2285)[183:matterhorn-workflow-service-impl:4.0.0.SNAPSHOT]         at java.util.concurrent.FutureTask.run(FutureTask.java:266)[:1.8.0_181]         at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)[:1.8.0_181]         at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)[:1.8.0_181]         at java.lang.Thread.run(Thread.java:748)[:1.8.0_181] My systems run upwards of 100 workflows at any given time, almost all of which are using the same workflow definition as the one that failed above.
