“The root module input variable ‘[variable_name]’ is not set, and has no default value” or “Error: Variables not allowed”

This is commonly associated with using TF_VAR_* where the variable type is a list or map. Please make sure the value is properly formatted for the variable type.
list type expects an array with quotes around the list item. e.g. ["listitem1", "listitem2"]
map type expects a key/value map surrounded curly brackets. e.g. {"key1": "value1", "key2": "value2"}

”Error: Incorrect attribute value type”

This can occur if your template variables do not specify the type and you are trying to assign the value in the Environment Variables section. e.g. 
export TF_VAR_myvar='["listitem1","listitem2"]'

variable "myvar" {
  type = list(string) // make sure you add this field to your variable
}
