Operation details doesn't show operation attributes when state is instantiated
Steps to reproduce
Steps to reproduce:
1. Upload a file, selecting a workflow
2. Go to the workflow detail-worflow operations-operation details, choosing an operation that is instantiated, but not executed yet
Screen doesn't show operation attributes, such as fail-on-error, max-attempts, workflow-error-handler, etc.
Screen should show data that is defined in the workflow
Workaround (if any):
As discussed on list  we have agreed that the endpoint should be changed to use the operation position ie
The underlying reason it that it uses the admin-ng endpoint being used selects the operation based on the jobid, therefore if job not started no jobid, no info.
The operation should be accessed by it's position instead.
