Can no longer add or edit products in the magento 2 admin

[s_ragsdale]

Hello I have magento 2.1.8 community version installed; I have successfully added 3 simple products in my admin but now I can no longer add or edit the existing products.  Please note the error I get using chrome dev tools:

select.js:67 Uncaught TypeError: data.some is not a function

    at findFirst (select.js:67)

    at UiClass.clear (select.js:285)

    at UiClass.setInitialValue (select.js:299)

    at UiClass.setInitialValue (wrapper.js:109)

    at UiClass.initialize (abstract.js:70)

    at UiClass.initialize (wrapper.js:109)

    at UiClass._super (wrapper.js:106)

    at UiClass.initialize (select.js:119)

    at UiClass.initialize (wrapper.js:109)

    at new UiClass (class.js:49)

The file is located here:  {base_url}/files/html/vendor/magento/module-ui/view/base/web/js/form/element/select.js

Has anyone experienced this type of error before? What can I do to try and fix this so that I can add and edit products again?

Hello, 

Yes, I have experienced the exact some error and Im unable to add or edit products in Magento 2.2.0. 

something is wrong with:

data.some(function (node) {
            value = node.value;

            if (Array.isArray(value)) {
                value = findFirst(value);
            }

            return !_.isUndefined(value);
});

i have changed  this to (please correct me if I'm wrong)

data = _.some(data, function (node) {
            value = node.value;
            if (Array.isArray(value)) {
                value = findFirst(value);
            }

            return !_.isUndefined(value);
 });

ran the following command: 

rm -R pub/static/*

php bin/magento setup:static-content:deploy -f

Now, I can edit/add products.
