Tested on Pizza -

• I can create a Medway RAB submissions
• I can download a Medway RAB submission (after sorting out populating flow_integrations table - still need to fix sync script for this sorry!)
• Zip download completes in ~8 seconds ✅

The digitalPlanningDataPayload step is still slower than I was expecting based on the benchmarks in planx-core, but a huge improvement (and the changes in theopensystemslab/planx-core#885 will also help!)

@DafyddLlyr thanks for testing !!

Regression tests currently failing on this branch: https://github.com/theopensystemslab/planx-new/actions/runs/20009795006

Invite to Pay isn't happy about the Session type change I think, so I'm just trying to get that sorted now. Regression tests "React" step curiously passed without issue, despite failures on main over the weekend !
