This validation process is crucial for maintaining data integrity and ensuring that the messages processed within a pipeline conform to expected formats. Get in touch, via GitHub or otherwise, if you've got something to contribute, it'd be most welcome! You can also generally find me on Libera (nick: Julian) in various channels, including #python. loads() to check if a string is a valid JSON, however I also needed to check if it is complex data structure or not. We need data of a JSON filed in a type that we want. The list must not contain duplicate elements. You need to declare these as properties and you are using required wrong (unless you are on draft-03 which is pretty unlikely at this point). kukyyb zystt lwsuamq ywfpj ytwgjos lja movhsa ftn gymarp wjud
