Magento 2: custom payment module not working after installing to new setup

[mohinik-chetu]

Hi,

I have developed a magento 2 custom payment module and installed in fresh Magento 2 setup. But on checkout page I am getting error "Object DOMDocument should be created." I am not able to find the solution, I have checked all the xml configuration files and matched with existing payment module(authorizenet).
Following is the error log.

a:4:{i:0;s:37:"Object DOMDocument should be created.";i:1;s:12943:"#0 /var/www/magento2/public_html/vendor/magento/framework/View/Element/UiComponent/Config/Reader.php(95): Magento\Framework\View\Element\UiComponent\Config\DomMerger->getDom()

Checked system log files and found issue was related to no class definition for some objects.

I checked my code mny times and it is fine.

Appreciate any help in this.

Thanks,
