I created a custom module in magento2 for admin panel. Grid form is version fine. But When I tried to add/edit a record then its throwing the error like "Changes have been made to this section that have not been saved. This tab contains invalid data. Please resolve this before saving."

Magento version is 2.1.1.

I am unable to find any clue in logs.

System.log file has follow error.

You should check for PHP errors in the server logs.

If you have a PHP error while generating some block, it can result in stopping the code execution, displaying this message.

Most probably it's an error in one of your blocks you're calling on that page in the "Redirect Information" tab.
