When failing inside of the Typescript portion of the wasp db seed command execution, we return a exit code of 0 instead of 1.

How I initially found out about it:

By calling wasp db seed with a valid seed name e.g. devSeedSimple

// main.wasp  
db: {
    seeds: [
      import { devSeedSimple } from "@src/features/db/seeds",
      import { prodSeed } from "@src/features/db/seeds"
    ],
    prismaSetupFn: import { setUpPrisma } from "@src/features/db/prisma",
  },

But not actually exporting the declared function, we error out on wasp db seed but return exit code 0:

Easy reproduction

Same can be done by throwing any Error inside of the seed function:

export const devSeedSimple: DbSeedFn = async (prismaClient) => {
  throw Error("AAAA");
}

Extra context I checked for now

Calling the seed directly from package.json script (npm run db-seed) inside of .wasp/out/server returns 1 properly:
