Hi everyone,

I am trying to save pipeline execution details (such as pipeline name, user, workflow ID, etc.) when a user runs a pipeline via the XNAT UI. The goal is to store these details so that I can later update the workflow status from my queue system.

I am facing problem with passing worklfowId. To do this, I am attempting to pass the workflow ID from the pipeline XML to my CLI application. However, I have not been successful so far.

In my pipeline XML, I tried passing the workflow ID like this:

<argument id="workflowId">
<value>^WORKFLOWID^</value>
</argument>

But when the CLI receives the argument, it gets the literal string ^WORKFLOWID^ instead of the actual workflow ID value.

I am currently using XNAT version 1.8.4.

Has anyone successfully passed the workflow ID (or other workflow metadata) from a pipeline XML to a CLI script in XNAT? If so, what is the correct way to reference the workflow ID in the pipeline XML?

Any guidance would be appreciated.
