Lucidchart Mermaid Syntax Errors

Below is an example that has syntax error but generates on other interpreters.. 

graph TD

    subgraph "PEOPLE LAYER"

        P1("Support Engineers")

        P2("Developers")

        P3("Product Managers")

        P4("QA Team")

        P5("End Users")

    end

        PR3("Change Management")

        PR4("Release Management")

It would be helpful if Lucid returned the actual syntax errors, similar to how https://mermaid.live/ handles it.
