Error Creating FSX using terraform

I seem to be running into an error with my FSX build using terraform and I dont understand the error as the API error is a generic one that doesnt make sense to me what Im doing wrong. Has anyone had this error before?

Windows Terminal

Figured this out. Even though interpolating isnt allowed in later version of Terraform you need to interpolate your subnetIDs
