mapvalidator.KeysAre(
	stringvalidator.LengthAtLeast(3),
	stringvalidator.RegexMatches(regexp.MustCompile(`^x-`), "must begin with x-"),
),

Terraform Configuration

resource "examplecloud_thing" "test" {
  map = {
    zz = "..."
  }
}

Expected Behavior

Both validation errors are returned.

Actual Behavior

Only the first is returned:

Error: Invalid Attribute Value Length
        
          with examplecloud_thing.test,
          on terraform_plugin_test.tf line 3, in resource "examplecloud_thing" "test":
           3: 						zz = "..."
        
        Attribute map["zz"] string length must be at least 3, got: 1

Steps to Reproduce

1. terraform apply

Logs

No response

Additional Information

For configuration validation, practitioners should see all configuration errors at once, rather than requiring multiple iterations of fixing a configuration.

There is a resp.Diagnostics.HasError() check after Validate() is called in the loop, which doesn't need to be there.
