@Eric_P I think there might be an error with parsing the { } brackets in this? Since its raw json, the javascript between {{}} isn't being run. I'd suggest adding a javascript block prior to this block and have it return the same json object you've written here and place it in the raw body instead.
Yes — and I also test the entire workflow end to end by starting at the last step and it seems to go through this step OK. Unfortunately, when I actually "Run" the workflow it seems to get stuck. Any tips?
