Can someone guide me on where I can find the issue the validator is concerned over? This is Magento 2.3.4, and the database has gone through data migration. There are several products that when I display them and then try to save I get an error, the message in the log is what appears in the title of this post.
[2020-03-01 17:36:03] main.DEBUG: Request validation failed for action "Magento\Catalog\Controller\Adminhtml\Product\Validate\Interceptor"  
I have been unsuccessful in finding a place in the code but have determined a breaking point by trial and error. I created a new product and gave each a drop down with 5 values. The system will allow 9 of these options with 5 values each for the drop down. Anymore than that, another option or another drop down value will give me the error.
So it seems to either be a Magento 2 issue or an interface issue into the database? All I get on the backend is that I received a technical issue and try again later and the debug file points to an interceptor. I am getting hits on it within the request and response functions but never have I been able to print large amounts of data like an object from Magento2 without crashing the system. Any hints here would be greatly appreciated.
These products are currently in Magento 1 with up to 8 options and various drop downs, radio buttons and text fields associated with each option.
Any help would be appreciated, Thanks in advance..!
