ReactQuery: Typecheck fails on the generated code

[DragosRomaniuc]

What are the steps to reproduce this issue?

1. yarn run build

2. Errors:
   ../../resources/common/src/clients/models/check503Info.ts:14:5 - error TS2411: Property 'status' of type 'string | undefined' is not assignable to 'string' index type 'string'.

14 status?: string;
~~~~~~

817 const formData = new FormData();
~~~~~~~~
../../resources/common/src/clients/api/events/events.ts:890:24 - error TS2693: 'FormData' only refers to a type, but is being used as a value here

What happens?

When I build a project with the generated orval clients it fails.

export const createEvent = (createEventBody: CreateEventBody) => {
  const formData = new FormData();
  if (createEventBody.coverImage !== undefined) {
    formData.append("coverImage", createEventBody.coverImage);
  }
  if (createEventBody.data !== undefined) {
    formData.append("data", JSON.stringify(createEventBody.data));
  }

  return customInstance<PrivateEventDto>({
    url: `/events`,
    method: "POST",
    headers: { "Content-Type": "multipart/form-data" },
    data: formData,
  });
};

What were you expecting to happen?

Not to fail.

Any logs, error output, etc?

Any other comments?
