transform keyword, is not working with 'toLowerCase' after updating to v3.4.0

[carlos-toscano]

Hi, I did the update to 3.4.0, and i´m using transform keyword, with 'toLowerCase', but this doesn´t do the transform.

Is needed to add a new keyword to keep this functionality?, thanks.

It's difficult to say what you do wrong without a code sample. If you follow docs and code in tests it will work.

@epoberezkin , thanks for your answer, I discover that this problem is caused by updating the 'ajv' package, using version 6.9.0 or above, were there changes to add this kind of packages?

here an example

const Ajv = require('ajv');
const ajv = new Ajv({
  allErrors: true,
  removeAdditional: 'all',
  useDefaults: true,
  coerceTypes: true
});

require('ajv-keywords')(ajv, 'transform');

const schema = {
    "$schema": "http://json-schema.org/draft-07/schema",
    "title": "Transform Example",
    "description": "The transform keywork doesnt transform object",
    "type": "object",
    "properties": {
        "email": {
            "type": "string",
            "description": "User email",
            "minLength": 5,
            "transform": ["trim", "toLowerCase"]
        },
        "password": {
            "type": "string",
            "description": "User password",
            "minLength": 1
        }
    },
    "required": [
        "email",
        "password"
    ]
};

ajv.addSchema(schema, 'login')

const data = {
	email: "carloS ",
	password: "secret"
};

test(data);

console.log(data);

function test(data) {
  var valid = ajv.validate('login', data);
  if (valid) console.log('Valid!');
  else console.log(ajv.errors);
}

The culprit seems to be removeAdditional option, and it indeed starts to happen in 6.9.0

It can be related to ajv-validator/ajv#955

[epoberezkin]

definitely Ajv issue fixing it there.

@epoberezkin, oka, I understand, thank you for support.

[epoberezkin]

fixed in ajv 6.9.2
