Terraform Configuration Files

    http = {
      type     = "Basic"
      username = "magodo"
      password = "***"
      foo      = "bar" # undefined
    }

Expected Behavior

Running terraform validate, it should error out as there is an undefined attribute foo in the http object.

An argument named "foo" is not expected here.

Actual Behavior

Success! The configuration is valid, but there were some validation warnings as shown above.

Hi @magodo 👋 Thank you for reporting this. It was discovered that terraform-plugin-sdk/v2 contained some of the validation logic, rather than Terraform CLI itself using the schema data passed across the protocol. To that end, there is hashicorp/terraform#30669 upstream to track this change so any provider implementation receives the benefits, including those written directly in terraform-plugin-go. Please 👍 and subscribe to that issue for further updates on this.

I forgot we have a similar issue here, #276, as well, so in an effort to consolidate it to one tracking issue on each side, I'm going to close this in preference of #276 which also references hashicorp/terraform#30669. Thanks again for raising this and hopefully it can be addressed shortly.
