How can I use the data object from a handled 400 error within the On error workflow? I can’t see a way to access the data within the actions.

The same error that you see in the sidebar is available under the name “current error”

It’s empty in the editor until you test the workflow and it fails

you have to make the difference between the result of a step and the result of the Workflow.  
if the workflow is on error then the on error is played but if you test the step, the step is on error but the workflow is not yet on error.

when the Workflow is on error then you have a second message
