Having this issue on two magento installations ver. 2.0.4 and ver. 2.0.6. (the second one is a new installation without any modules, blank theme)

Steps to reproduce

1. Proceed to checkout
2. Fill in shipping information
3. Choose shipping method
4. Hit the "back" button on your web browser
5. Click Proceed to checkout again

Expected result

Checkout page with pre-filled information

Actual result

Javascript error blocking rendering of the page
rules.js:56 Uncaught TypeError: Cannot read property 'length' of undefined

I'm getting the same error.

Same error here.
When the field "street.1" has no content the validation cause an exception. The value.length is undefined.
A workaround is to disable the validation_rules for the customer_eav_attribute "street" in the database.

Error appears on Magento 2.0.7, Magento 2.1-RC2

This is the error from min_text_length and max_text_length. The problem is somehow value is returned as null. So I add null-check logic before accessing its property.

"min_text_length": [
    function (value, params) {
        return !value || (!!value && value.length == 0 || value.length >= +params);
    },
    $.mage.__('Please enter more or equal than {0} symbols.')
],
"max_text_length": [
    function (value, params) {
        return !value || (!!value && value.length <= +params);
    },
    $.mage.__('Please enter less or equal than {0} symbols.')
],

I also faced the same issue, but it is not happening always

Hi Magento team,

Is the fix going to be included into Magento 2.1 stable release? It is blocking logged in customers to place an order.
