Tripletex schema: Does not satisfy the constraint 'RouterBaseObject' and circularly references

[thhermansen]

Hi,

I wanted to use the client with Tripletex's API¹.

I have downloaded their schema (tripletex-schema.ts.zip) and written the following code to make a simple test:

import { type NormalizeOAS, createClient } from 'fets';
import type openapi from './tripletex-schema';

type Normalized = NormalizeOAS<typeof openapi>;
const client = createClient<Normalized>({
  endpoint: 'https://tripletex.no/v2',
});

const response = await client['/token/session/>whoAmI'].get({ headers: { Authorization: 'Basic ...' } });

const data = await response.json();

console.log(data);

I get two issues:

1: TS compile error on line const client = createClient<Normalized>({. It states that:

src/lib/client/index.ts:5:29 - error TS2344: Type '{ basePath: "/v2"; definitions: { AccommodationAllowance: Omit<Omit<{ properties: { address: { type: "string"; }; amount: { type: "number"; }; changes: { items: Omit<{ $id: "#/definitions/Change"; properties: { ...; }; type: "object"; } & { ...; }, "additionalProperties"> & { ...; }; readOnly: true; type: "array"; }...' does not satisfy the constraint 'RouterBaseObject<any, any, any> & { (req: NodeRequest, res: NodeResponse, ...ctx: Partial<any>[]): Promise<void>; (request: Request, ...ctx: Partial<...>[]): Response | Promise<...>; (fetchEvent: FetchEvent & Partial<...>, ...ctx: Partial<...>[]): void; (res: UWSResponse, req: UWSRequest, ...ctx: Partial<...>[]): Pr...'.
  Type '{ basePath: "/v2"; definitions: { AccommodationAllowance: Omit<Omit<{ properties: { address: { type: "string"; }; amount: { type: "number"; }; changes: { items: Omit<{ $id: "#/definitions/Change"; properties: { ...; }; type: "object"; } & { ...; }, "additionalProperties"> & { ...; }; readOnly: true; type: "array"; }...' is missing the following properties from type 'RouterBaseObject<any, any, any>': openAPIDocument, handle, route, __client, __onRouterInitHooks

5 const client = createClient<Normalized>({
                              ~~~~~~~~~~

2: TS complains about circular dependencies:

src/lib/client/index.ts:9:7 - error TS2615: Type of property '"department"' circularly references itself in mapped type '{ [KEY in keyof { address: { type: "object"; properties: { addressLine1: { maxLength: 255; minLength: 0; type: "string"; }; addressLine2: { maxLength: 255; minLength: 0; type: "string"; }; bnr: { format: "int32"; minimum: 0; type: "integer"; }; ... 13 more ...; version: { ...; }; }; $id: "#/definitions/Address"; add...'.

9 const response = await client['/token/session/>whoAmI'].get({ headers: { Authorization: 'Basic ...' } });

I'm having a bit of a hard time figure out what is wrong here. I found examples of swagger 2.0 schema², so I'm guessing it is supposed to be ok for swagger 2.0 too?
