We also have the same issue. What is the workaround, how is the issue solved?
Can you translate the comment to better English? I cannot make sense out of it.

@kathytrac "I dont have this problem anymore, after deleting some per cvs imported products, whose sku not normal are ( that means their long sku consist of distance )."

You should check your imported products , if there are some special sku . For example, sku = abc 09 because there is a blank between abc and 09. That may cause error. Then you should delete all of these sku (manuel or with cvs ) . Then you will not have this error more . You should edit these sku to let them have no blank . Sorry for my english if you dont understand.

Thanks for reply @kathytrac . We dont have spaces between the SKU names. Also looking at the error, I dont think that should be causing the offset issue. I would want Magento team to look at it, but this ticket is closed even though others are still facing problem around it. I hope https://github.com/magento/magento2/issues/8426 will be addressed with bit more relevant solution.
