Output type created for unusedIO: 'input' schemas #534
Description
When putting an object inside an union (or something similar to that), and setting unusedIO: 'input', it still results in an Output type being generated.
Just having a top-level object does not seem to have the same effect.
Tried to get rid of it, but got lost in the createComponents -> createIOSchemas -> createSchemas call tree.
The Output schema gets generated in createIOSchemas -> renameComponents when io: "output", but I could not find a way to prevent that since I did not figure out where the schema got there in the first place.
I tried adding ctx.io !== ...zodType.unusedIO in various places (createComponents, createIOSchemas) but it still somehow got included...
Reproducer test (into document.test.ts):
it('unusedIO input', () => {
const Obj = z
.object({
field: z.string(),
})
.meta({ id: 'Obj', unusedIO: 'input' });
const Union = z.union([Obj]).meta({ id: 'Union', unusedIO: 'input' });
const document = createDocument({
info: {
title: 'My API',
version: '1.0.0',
},
openapi: '3.1.0',
components: {
schemas: {
Union,
},
},
});
expect(document).toMatchInlineSnapshot(`
