The current approach validates the value only when the resource is created (need to add the validation during the update ).
Can we add ValidateFunc to the Schema of var_files Elem ?
pros:

• validation is executed during plan phase (currently during apply)
• validation is executed on create and on update

@DayS1eeper unfortunately we can not. ValidateFunc is supported only for primitive types and does not work on lists or sets: https://developer.hashicorp.com/terraform/plugin/sdkv2/schemas/schema-behaviors#validatefunc.
Added same validation on resource update (interesting to know, the bug does not reproduce on update).
JFYI the actual root cause of the bug is known for years too hashicorp/terraform-plugin-sdk#216
