Admin Product View Page Error On Sort Or Filter After Migration M1 to M2

I had a problem after migration, to sort the product filter in the admin panel page but I am receiving the error:

Something went wrong with processing the default view and we have restored the filter to its original state.

 

Solution:

SKU should be empty or string. In this case, it is null or not a string.

Run follwoing query will resolve your issue if it is null sku related error:

UPDATE catalog_product_entity SET sku='' WHERE sku IS NULL;

You can check your corrupted sku and fix that.
