The layer errors are complaining about necessary layers in the macro. These are for OPC etc and cannot be removed.

Thanks for the quick response.

I see. Then it's probably the problem of the openlane. Is there maybe any workaround to make the tool to recognize those necessary layers?

It's shown as an error, but it is really a warning.
