How to use Validator ? Context is not finalized

As soon as I try to use validator, Hono complains. api-hono:dev: error: Context is not finalized. Did you forget to return a Response object or await next()?

app.post(
  '/',
  validator('form', (value, c) => {
    console.log("VALIDATOR")

    const body = value['body'];
    // if (!body || typeof body !== 'string') {
    //   return c.text('Invalid!', 400);
    // }

    // const parsed = customerFormSchema.safeParse(body);
    // if (!parsed.success) {
    //   console.log(401)
    //   return c.text('Invalid!', 401);
    // }
    // // parsed.data for body;

    return {
      body
    };
  }),
...

app.post(
  '/',
  validator('form', (value, c) => {
    console.log("VALIDATOR")

    const body = value['body'];
    // if (!body || typeof body !== 'string') {
    //   return c.text('Invalid!', 400);
    // }

    // const parsed = customerFormSchema.safeParse(body);
    // if (!parsed.success) {
    //   console.log(401)
    //   return c.text('Invalid!', 401);
    // }
    // // parsed.data for body;

    return {
      body
    };
  }),
...

Any idea? :\ EDIT: I'm using Superforms to send the request. Devtool says the data it is indeed Form Data. If I replace form with json, it doesnt throw the error, but the value is empty

Just do await next(); If you want to save the updated body you will have to do to C.req.setValdate something On phone so can’t really type

Shit, really ? I didn't see that in any example I think... 😂

Interesting can share the docs page where you say it If there is an issue I will update them

Thank you very much for taking the time, you're amazing! I'll do that and report back ❤️ https://hono.dev/docs/guides/validation#manual-validator

Interesting, I will take a look at this and will update it

don't do anxiety to reply lol, just leaving this here for when you're home and have time 😇 Post form test in the repo: https://github.com/honojs/hono/blob/73ff6c0e82d66468e28ed439481220f56ab03882/src/validator/validator.test.ts#L217 But it doesnt work on my end. On my end, I tried adding next, but it doesnt like it.

  validator('form', async (c, next) => {

    await next();
  }),

  validator('form', async (c, next) => {

    await next();
  }),

This expression is not callable.
  Type 'Context<any, string, {}>' has no call signatures.

I might have found the underlying issue... I'm using const body = await c.req.parseBody() so I need an async function in the main handler. and then I try to return values:

return c.json({
      hello: true
      // id: insert.id,
    });

return c.json({
      hello: true
      // id: insert.id,
    });

https://hono.dev/docs/api/request#parsebody This throws an error api-hono:dev: error: Context is not finalized. Did you forget to return a Response object or await next()? Found the culprit !!!

app.use(async (c, next) => {
  c.set('dbClient', createClient());
  c.set('e', e);
  next();
});

app.use(async (c, next) => {
  c.set('dbClient', createClient());
  c.set('e', e);
  next();
});

The first middleware that is suppose to make my db connection inside context causes this. Strange as I was succesful into inserting requests but I must have changed something somewhere. 😂 adding await before next() solves the issue 🤦

Great! 😂
