Generate.

Open /src/gen/hooks/stepsHooks/useGetStep.ts.

Observe the following typescript errors:

 useGetStep.ts    42  17 error    2742   The inferred type of 'getStepQueryOptions' cannot be named without a reference to '../../../../../../node_modules/@tanstack/query-core/build/modern/hydration-zFr_7WN8.js'. This is likely not portable. A type annotation is necessary. (lsp)
 useGetStep.ts    42  17 error    2742   The inferred type of 'getStepQueryOptions' cannot be named without a reference to '../../../../../../node_modules/@tanstack/react-query/build/modern/types.js'. This is likely not portable. A type annotation is necessary. (lsp)

on this function:

export function getStepQueryOptions(
  { step_id }: GetStepPathParams,
  config: Partial<RequestConfig> = {}
) {
  const queryKey = getStepQueryKey({ step_id });
  return queryOptions({
    enabled: !!step_id,
    queryKey,
    queryFn: async ({ signal }) => {
      config.signal = signal;
      return getStep({ step_id }, config);
    },
  });
}

Can be temporarily resolved by adding:

import type _1 from "@tanstack/query-core";
import type _2 from "@tanstack/react-query";

How often does this bug happen?

Every time

What is the expected behavior?

No typescript errors :P

Swagger/OpenAPI file?

@komali2 Can you create an example with codeSandbox? First thought is that you are having a tsconfig issue(not related to Kubb).

Happy to, but it'll take me a bit since it's all nestled within a huge proprietary codebase for now. I'll work on that tomorrow (it's my night right now). For now, here's my tsconfig, just in case:

Adding this to the top of every file "fixes" the issue:

import * as _hydration from "@tanstack/query-core";
import * as _build from "@tanstack/react-query";

It can be added with the output.banner function. See kubb config:

import { defineConfig } from "@kubb/core";
import { pluginTs } from "@kubb/plugin-ts";
import { pluginZod } from "@kubb/plugin-zod";
import { pluginReactQuery } from "@kubb/plugin-react-query";
import { pluginOas } from "@kubb/plugin-oas";

export default defineConfig({
  root: ".",
  input: {
    path: "../backend/openapi.json",
  },
  output: {
    path: "./src/gen",
    clean: true,
  },
  // hooks: {
  //   done: ["npm run lintfix", "npm run format"],
  // },
  plugins: [
    pluginOas(),
    pluginTs({
      output: {
        path: "models",
        barrelType: false,
      },
      group: {
        type: "tag",
        name: ({ group }) => `${group}Controller`,
      },
      enumType: "literal",
    }),
    pluginZod({
      output: {
        path: "./zod",
        barrelType: false,
      },
      group: {

      },
      typed: true,
      dateType: "stringOffset",

    pluginReactQuery({

        barrelType: false,
        banner: `

`,
      },
      group: {

      },
      mutation: {

  ],
});

@komali2 I tried reproducing the issue but couldn’t replicate the error. I tested a few scenarios to check if it might be related to your tsconfig, but without success. It seems more likely to be a configuration issue unrelated to Kubb’s generation. I recommend opening an issue directly with React Query (https://github.com/TanStack/query) for further assistance.
