AWS Terraform Upgrade Empty Variables

Hi everyone,
Has anyone run into a scenario where, during the terraform version upgrade to 0.15 (from 0.14.11) the tf plan shows in-place changes where it adds empty values like “” for optional attributes. Example is:

this will be updated in-place
resource “aws_codebuild_project” “this” {
+ badge_url = “” <=== like this
id = “arn:aws:codebuild:XXX”
name = “name”
+ source_version = “” <=== like this
# (7 unchanged attributes hidden)
~ environment {
+ certificate = “” <=== like this
# (5 unchanged attributes hidden)

I don’t think just applying it will have any unintended consequence, but I’d like to hear a second opinion? You can check the <=== like this above.
