workflow options

I'm trying to specify the root folder where the cromwell analysis is run using the --options flag for cromwell. According to the docs, I should just mimic the structure of the cromwell config file, but I cannot get it to work.

Workflow options:

$ cat workflow_options.json 
  "backend": {
    "providers": {
      "LocalExample": {
        "config": {
          "root": "/data/Hex/cromwell-executions"
  "final_workflow_outputs_dir": "/data/Hex",
  "workflow-log-dir": "/data/Hex/cromwell-workflow-logs"

Error message:
[2018-01-18 10:45:32,92] [warn] SingleWorkflowRunnerActor: received unexpected message: WorkflowSubmitFailed(java.lang.RuntimeException: Unsupported key/value pair in WorkflowOptions: backend -> {"providers":{"LocalExample":{"config":{"root":"/data/Hex/cromwell-executions"}}}}) in state SubmittedSwraData $? is -15
