I made a modification to the types to use a seq instead of a table:
import playdate/api
import std/json
import std/options
import std/sequtils
import utils
import shared_types
let kFileReadAny*: FileOptions = cast[FileOptions]({kFileRead,
kFileReadData})
type
LevelProgressEntity* = ref object of RootObj
levelId*: Path
bestTime*: Option[Seconds]
hasCollectedStar*: bool
SaveSlotEntity* = ref object of RootObj
progress*: seq[LevelProgressEntity]
modelVersion*: int
proc saveJson*[T](value: T, path: string) {.raises:[].} =
let jsonNode = %(value)
[...] more code
Run
Gives this error:

Note that
* sequtils is unused
* when I change the last line to
let jsonNode = %(SaveSlotEntity())
Run
It works fine. So is there anything regarding generics I'm doing wrong?
