export_opex & Export Workflow context?

[Roxana Maurer-Popistașu]

Hi James,

Is there a way to pass a certain Export Workflow Context ID to the OPEX export? 

In order to prioritize exports over ingests, we got a new tagged Export Workflow going to a dedicated Job Queue server, but the OPEX Export doesn't seem to find the new context, even if it's the only one active. We simply get an error message: unable to find workflow context  for definition com.preservica.core.workflow.export. Any idea how we could bypass that?

Thanks,

Roxana

Hi

One thing to try, make sure the workflow context parameters in the Preservica workflow definition exactly match the API parameters. 

It will look for a matching export workflow.

Hi again,

Since the new workflow is a copy of the old one, it has the exact same parameters. But the workflow name and ID are different:

- old: name="Export (v6)" id="com.preservica.core.workflow.export"

- new: name="Export (v6) - priority tag" id="com.preservica.core.workflow.export-tagged"

Best,

Roxana

I dont think you can.

This is the underlying API call

https://demo.preservica.com/api/entity/documentation.html#/%2Fstructural-objects/post_structural_objects__ref__exports

Does it work if the "com.preservica.core.workflow.export" workflow is enabled?

This is a separate workflow API, which may work. I would need to investigate

I see, that makes sense. I'll see if we can come up with another solution on our end.

Thank you again,

Roxana

Hi

I managed to run an export workflow against the export workflow given by the definition id using the script below:

EntityRefs is the uuid of the asset or folder.  You could try this using your new definition id:   com.preservica.core.workflow.export-tagged

from pyPreservica import *

workflow = WorkflowAPI()

contexts: list[WorkflowContext] = workflow.get_workflow_contexts('com.preservica.core.workflow.export')
for context in contexts:
    params = {'EntityRefs': '296ef8cb-5f5e-42e9-9cc0-daff460bb35e' }
    pid = workflow.start_workflow_instance(context, **params)
    print(pid)
