    posted a message on I get this ERROR while joining in my Minecraft Forge Server

    I couldn't find a solution, can someone help me please?


    When I open the server with start.bat (java -Xmx3072M -Xms3072M -jar forge-1.12.2-14.23.5.2768-universal.jar nogui)


    I get this error

    Mod codechickenlib is missing the required element 'version' and a version.properties file could not be found. Falling back to metadata version 3.2.2.353

    at this point the server starts without crashing but then when I try to join I get this:
