Errors using this repository alongside the FIXTradingCommunity/orchestrations repository

[aligirayhanozbay-abex]

Hi, I'm experimenting with using this repository alongside the FIX standard orchestration files in the orchestrations repository to generate proto3 files. When I try to run for instance

java -jar target/orchestra2proto-jar-with-dependencies.jar  -lang proto3 ~/orchestrations/FIX\ Standard/OrchestraFIXLatest.xml

I get the following error:

Exception in thread "main" java.lang.RuntimeException: XML Validation Exception: unexpected element (uri:"http://fixprotocol.io/2022/orchestra/appinfo/fixml", local:"FIXMLencodingType"). Expected elements are <{}text> at row: 20 column: 62

Are there some other steps I need to follow for this to work?

You can try to remove the appinfo elements for FIXML with a script. They are only needed internally by FIX to create the FIXML schemas from an Orchestra XML files. It seems that the protobuf converter does not ignore them (yet). There is no schema for the appinfo content to validate against.
