Unsupported type `[keyof T]`

[Theartbug]

My team is trying to implement the AtLeastOne<T> generic type created by the Microsoft Azure team: https://learn.microsoft.com/en-us/javascript/api/@azure/keyvault-certificates/requireatleastone?view=azure-node-latest

type RequireAtLeastOne<T> = { [K in keyof T]-?: Required<Pick<T, K>> & Partial<Pick<T, Exclude<keyof T, K>>>; }[keyof T]

We've poked around a bit and notice when we remove [keyof T] at the end, it can generate the schemas.json. We are wondering if it has something to do with recursion?

The output error text is too long to retrieve full logs, but it looks like this:

[domoritz]

Thanks for the report. Can you provide a minimal reproducible example that demonstrates the issue?

Also, have you tried ts json schema generator?

[netanel-mce]

I have a same issue,

Minimal reproducible example:

I tried generate Schema for "Main" type

type Util = {
    a: {
        b: string;
    };
};

export type Main = {
    [Key in keyof Util]: {
        [key: string]: Util[Key];
    };
};

Versions:

typescript-json-schema : 0.55.0 typescript: ~4.9.3 node: 18.12.1
