Robyn Budget Allocator is not running

## Project Robyn

## Describe issue
After model run in Robyn UI, the budget allocator is not producing results for me. I've attached an image of the session and the script in the workspace after running the model.

If you need anything else, please let me know.

Also is there a way to call up the json file? So that I would not have to rerun the model after closing to do other scenarios if ever.

Thank you
Johanne
