The Foundry HTS emulation contract uses vm.keyExistsJson heavily. However, this function was only included in forge-std version 1.8.0 (see foundry-rs/foundry#7602).
Document forge-std version requirements to let users know which version they need to have. Include a new question in FAQ.md with this issue as well.
