Very Fun Instance of Type instantiation is excessively deep and possibly infinite.ts(2589)

Encountering this error, the following is what I have done to try to resolve it. I have read this: https://docs.convex.dev/functions/actions#dealing-with-circular-type-inference so I ensured every single query, action, and mutation, internal ones too, have both a returns, and a typed return for the handler. EX

export const meFromIntegration = query({
    args: { integrationId: v.string() },
    returns: v.union(
        v.object({
            name: v.optional(v.string()),
            email: v.optional(v.string()),
            image: v.optional(v.string()),
            timezone: v.optional(v.string()),
            languageCode: v.optional(v.string()),
        }),
        v.null(),
    ),
    handler: async (
        ctx,
        args,
    ): Promise<{
        name: string;
        email: string;
        image: string;
        timezone: string;
        languageCode: LanguageCode;
    } | null> => {

export const meFromIntegration = query({
    args: { integrationId: v.string() },
    returns: v.union(
        v.object({
            name: v.optional(v.string()),
            email: v.optional(v.string()),
            image: v.optional(v.string()),
            timezone: v.optional(v.string()),
            languageCode: v.optional(v.string()),
        }),
        v.null(),
    ),
    handler: async (
        ctx,
        args,
    ): Promise<{
        name: string;
        email: string;
        image: string;
        timezone: string;
        languageCode: LanguageCode;
    } | null> => {

didnt fix it. So I kept looking around at other threads. Saw one mentioning it could have to do with Doc<>, so I removed all instances of Doc. Okay, Not it. Also found something referencing v.any(), so now I dont use v.any(), no dice. Okay so it said it had to do with ctx.run* not having a type. So I commented out every instance of ctx.run*, runMutation, runQuery, whatever. Still Not it. No idea whats left to try.

returns isn't going to do anything here, circular inference is cut off either inside the handler or via function return type of the handler itself. If you use anything that relies on inference via Convex generated types, eg., Doc, Id, you're still in the circle.
