Issue with the "optional" argument

Hi,

This is the first time we get this error without an changes.

Error: Unsupported argument

When commenting those arguments, everything works as expected.

I can't seem to find the go code for this module. From the error, i can see that the "optional" flag is no longer expected in those blocks

You can find the code here:

• Secret
• ConfigMap

Anyway, it works fine for me:

Refreshing Terraform state in-memory prior to plan...
The refreshed state will be used to calculate this plan, but will not be
persisted to local or remote state storage.

Note: You didn't specify an "-out" parameter to save this plan, so Terraform
can't guarantee that exactly these actions will be performed if
"terraform apply" is subsequently run.

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.
