In {base_url}/files/html/vendor/magento/module-ui/view/base/web/js/form/element/select.js

from

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

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

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

to

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

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

Were you able to resolve this? In case you weren't-- and in case you're using composer-- here are the steps to fix it:

In your composer.json:

-Require Composer Patches in the "require" section:

"cweagans/composer-patches": "^1.6"

In "extras":

"patches": {
      "magento/module-ui": {
          "some.data is not a function": "patches/module-ui-patch-1.diff"
      }
 }

Then create web/patches/module-ui-patch-1.diff:

diff --git a/view/base/web/js/form/element/select.js 
b/view/base/web/js/form/element/select.js
