Neither Linux or Windows can install modpacks from Technic anymore after update, we just get this error instead

there's no screenshot, which pack are you trying to install?

Sorry idk why that screenshot didn't attach. PokeNinjas Network. Never had problems until the 0.7 update of MultiMC

the solder service (solder.cf) they are using is providing technically invalid solder json by using a null version field, this version of the pack could have never worked in multimc, even in any previous versions, due to the check here https://github.com/MultiMC/Launcher/blob/develop/launcher/modplatform/technic/SolderPackManifest.cpp#L38

the official technic launcher added workaround for that https://github.com/TechnicPack/LauncherV3/commit/8f6499557404c877070223029f6979902cc520eb MultiMC will need to be patched, alternatively tell those pack creators to fix their crap, all their version fields are garbage
