My VS code is telling me that it is still 132138 characters. I can't deploy it: Error BCP184: File 'C:\Projects\finops-toolkit\src\templates\finops-hub\modules\scripts\OpenDataFunctions.kql' exceeded maximum size of 131072 characters.

How are you deciding what to keep and what to remove?

[flanakin]

I don't love removing values. While I feel there has to be a better solution, I submitted a PR to split the file into multiple files since we know it will grow over time. I don't love it, but it should get us past the current issue. I validated the deployment so it should resolve the current issues. Thanks for digging into this.
