JS Joi Validation fails on string length

After spending almost 2 days to investigate why the validation is not working, I've got to a point. Basically I found out that if my string has more than 40 chars, the validation will fail. If it has 40 or bellow it will work.

So now I am using validator.joi.string() but I also try to fix this issue with : validator.joi.string().min(0).max(500) but it doesn't seem to work.

Any solution to this?

I think the problem is with your validator initiation. If that fine then the following will work.

Joi.string().max(10)

Just was testing. Sorry for the wrong formatting.

But It does work fine.

const Joi = require('@hapi/joi');

const schema = Joi.object({
    username: Joi.string()
        .min(3)
        .max(100)
        .required(),
})


schema.validate({ username: 'abc' });
// -> { value: { username: 'abc' } }

schema.validate({});
// -> { value: {}, error: '"username" is required' }

// Also -

async function run(){
  const value = await schema.validateAsync({ username: 'abcedeedsdsd sfdfghgdf sgfdghsfdsfdjgsfdgs shgdfshgdbshgdf sdhghsjfgfkhgj' });
  console.log(value)
}

run();
