Don't understand the behavior of my intelliSense

[random pewter]

I am using kysely-codegen library in order to generate types from the kysely library I am using.
I am using vs code if it matters what editor I use.

Do anyone have any suspicion on what the issue could be?

export const AssignmentOnCharacter = extendType({
  type: "Character",
  definition(t) {
    t.field("assignment", {
      type: Assignment,
      resolve: async (character, _, __) => {
        const characterAssignment = await getCharacterAssignment(character.id);

        return characterAssignment ? { id: characterAssignment. } : null; // no intellisense and characterAssignment is type any.
      },
    });
  },
});

export const AssignmentOnCharacter = extendType({
  type: "Character",
  definition(t) {
    t.field("assignment", {
      type: Assignment,
      resolve: async (character, _, __) => {
        const characterAssignment = await getCharacterAssignment(character.id);

        return characterAssignment ? { id: characterAssignment.assignmentId } : null; // assignmentId is type string and characterAssignment is of type "AllSelection<From<DB, "characterAssignment">, "characterAssignment">"
      },
    });
  },
});

I can't try it for myself, but it looks like you're hitting the limits of what typescript can infer

if you split out your lambda functions and give them concrete types, instead of inferring them from extendType you may have better intellisense
