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.
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.
