Data action fails with 400 bad request during terraform apply

just noticed that genesyscloud_flow_data_action throws a 400 bad request when referencing a custom integration. the integration exists and is active. terraform 1.8.3. gc provider 1.12.0. error message says invalid reference id. checked the api docs but no luck. any ideas on the correct syntax for the data_action reference in hcl?

resource “genesyscloud_flow_data_action” “test” {
name = “test”
integration_id = “${genesyscloud_integration.custom.id}”
}

Check your HCL syntax for the integration_id attribute. The provider expects a static string or a direct reference, not an interpolated variable with curly braces. Use the reference directly without the dollar sign and braces.

integration_id = genesyscloud_integration.custom.id

This resolves the parsing error during the plan phase.
