Really large input variables breaks Terragrunt values passing to Terraform
Due to the standard way TG passes the input values to TF, really large input variables hit the OS ARG_MAX (or MAX_ARG_STRLEN, not sure) limits.
Ideally, TG should automatically handle these scenarios, either by switching to -var-file based on the input size or by defaulting to that altogether.
Take a look here for a workaround

I've been hitting the same issue recently, but what I've done is that I just pass everything to the generate and any dependencies etc I have in the terragrunt.hcl file, I pass those to the input{} block.

Hey @tavlima , could you provide a fixture that reliably reproduces this issue?
You can do that by either creating a public repository under your account that has a fixture to reproduce this issue, or by submitting a pull request with your new fixture here.
Please also propose some design considerations like what you think the behavior should look like. Are you thinking this is a new flag? New HCL configuration? etc. Someone reading your proposal should know exactly what solution would implement a fix to the problem.
