hi anybody knows how to properly use mount state in datomic ion lambda? I got the error class mount.core.DerefableState cannot be cast to class java.lang.String (mount.core.DerefableState is in unnamed module of loader clojure.lang.DynamicClassLoader @5943daef; java.lang.String is in module java.base of loader 'bootstrap') after deployed to aws, but works correctly in local repl.

Sounds like you haven't started your mount states.

tried to deploy several times, sometimes it works, sometimes it doesn't. i am not familiar with mount + ion lambda. do we need to manually start the states? i thought requiring the states is enough

magnars08:05:47

You have to run mount.core/start

Thanks @U07FCNURX! I am wondering why sometimes it works

magnars08:05:28

Agreed!

cl_j08:05:09

is it a bad idea to just call (mount.core/start) , or should i pick the required states to start?

magnars09:05:04

I think it is reasonable to start all the mount states as a default.

I guess someone should fix the git conflicts properly 🙂
