Try to move all arguments of the Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory in one node, like:

<type name="Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory">
        <argument name="collections" xsi:type="array">
            <item name="junosync_product_listing_data_source" xsi:type="string">Junorocket\Junosync\Model\ResourceModel\Product\Grid\Collection</item>
            <item name="junosync_category_listing_data_source" xsi:type="string">Junorocket\Junosync\Model\ResourceModel\Category\Grid\Collection</item>

Go to this file vendor/magento/framework/Config/Dom.php Find this function

    protected function _getMatchedNode($nodePath)
    $xPath = new \DOMXPath($this->dom);
    if ($this->rootNamespace) {
        $xPath->registerNamespace(self::ROOT_NAMESPACE_PREFIX, $this->rootNamespace);
    $matchedNodes = $xPath->query($nodePath);
    $node = null;
    if ($matchedNodes->length > 1) {
        throw new \Magento\Framework\Exception\LocalizedException(
            new \Magento\Framework\Phrase("More than one node matching the query: %1", [$nodePath])
    } elseif ($matchedNodes->length == 1) {
        $node = $matchedNodes->item(0);
    return $node;

and before the exception just log the node path. like echo $nodePath die; Actually recent lines in stack trace in exption.log will tell you the node that is problematic. Could you post stack trace

  • i have check and echo $nodePath and get /config/type[@name='Magento\Framework\View\Element\UiComponent\DataProvider\CollectionFactory'] above node are config please provide me solution May 11, 2017 at 5:14
