Cannot read property 'delete' of undefined #2165
Description
With the update to version 16.1.5 I have an exception.
With version 16.1.4 it works correctly.
Context
- node version: 10.16.3
- joi version: 16.1.5
- environment: node
What are you trying to achieve or the steps to reproduce ?
const Joi = require('@hapi/joi');
const itemsSchema = Joi.object().pattern(Joi.string(), Joi.object({
res: Joi.string(),
params: Joi.object({
custom: Joi.string().when('...res', {
is: 'custom',
then: Joi.required(),
otherwise: Joi.any().strip(),
}),
}),
}));
const data = {
item1: {
res: 'automatic',
params: {
custom: 'x',
},
},
item2: {
res: 'manual',
params: {
custom: 'y',
},
},
};
itemsSchema.validate(data);Which result you had ?
