Hi @skylorna , your sync domain is running protocol version 3 or earlier, but your package is compiled to Daml-LF 1.15 which was only introduced in protocol version 4.

If you are not using any language features like Daml Interfaces that were only introduced in Daml-LF 1.14, you can solve this issue by compiling to Daml-LF 1.14. Just add this to your daml.yaml file:

build-options:
  - --target=1.14

If you are using new language features, you need to upgrade your protocol version following this guide.

Thank you, I can work by commenting out the sentence of protocol-version in the configuration file
