@joeabbey From the crash file it shows the error as

runtime error: index out of range
github.com/hashicorp/terraform/config.interpolationFuncFormatList.func1(0xc420a22380, 0x4, 0x4, 0xc420a22380, 0x4, 0x4, 0x100000040)
    /opt/gopath/src/github.com/hashicorp/terraform/config/interpolate_funcs.go:677 +0x81d

Could you please share the state file or output of terraform show command

[Praveengostu]

We tried to apply the configuration, as there is no modules/ansible we removed the module "inventory" and did a terraform apply and which is successfully completed. So if there is some issue with module inventory in file ansible_inventory.tf could you please try to enable the debug by export TF_LOG=debug and share us debug output along with the state file.

Ah, thanks for the confirmation. I see where the bug is now. We have some logic for windows instances that needs to be fleshed out. In our CI, we were requesting a windows instance, and this appears to blow up the inventory production. Closing!
