Joi validation without Hapi

Question

I am using Joi to validate the schema and I are not using Hapi.

I am writing a test case where my joi schema should return an error. Below is my schema

const testSchema = Joi.object().keys({
  name: Joi.string().required(),
  data: Joi.array().min(1).max(8).required(),
});

My current payload

const currentPayload = {
  data: ['1', '2'],
};

and my simple validation is

try {
  const result = Joi.validate(currentPayload, testSchema);
} catch (err) {
  console.log(err);
}

Now, this err just contains a canned message without details. To get detailed message, I need to use failAction as described here

What I have understood so far is that failAction is hapi function and not joi.

Any ideas how can I get detailed error message to work

Edit:

Here is how the err object looks like

This is really embarrassing. This error gets thrown if the schema mentioned in the Joi.validate in invalid. In my case it was undefined as I was referencing it incorrectly from another file :(

the good part is now I know when Joi will throw an exception :)
