Terraform Version

0.12.26 and latest terraform aws provider (aws = "~> 2.67")

Affected Resource(s)

• aws_wafv2_web_acl

Terraform Configuration Files

resource "aws_wafv2_web_acl" "main" {
  name  = "name"
  scope = "REGIONAL"

  tags = {
    "env" = "test"
  }
}

I am make use of this resource my module here -> https://github.com/umotif-public/terraform-aws-waf-webaclv2/blob/master/main.tf#L49
May be easier to reproduce that issue directly with the module.

Expected Behavior

I expect to update tags in place without failing.

Actual Behavior

Getting following error when a modification to tags happens.

Error: Error updating WAFv2 WebACL: WAFInvalidParameterException: Error reason: Your statement has multiple values set for a field that requires exactly one value., field: STATEMENT, parameter: Statement
{
  RespMetadata: {
    StatusCode: 400,
    RequestID: "107414ca-164c-4797-aa41-0472d1079d86"
  },
  Field: "STATEMENT",
  Message_: "Error reason: Your statement has multiple values set for a field that requires exactly one value., field: STATEMENT, parameter: Statement",
  Parameter: "Statement",
  Reason: "Your statement has multiple values set for a field that requires exactly one value."
}

Steps to Reproduce

Simply add another tag to tags map and terraform apply

Submitted an update to the resource that should prevent the extra UpdateWebACL API call: https://github.com/terraform-providers/terraform-provider-aws/pull/13871

The above fix has been merged and will release with version 2.68.0 of the Terraform AWS Provider, later this week. Please note that there may still be underlying issues with actual updates with what we pass to the UpdateWebACL API call when it is needed and if so, please file a separate issue. Thanks!
