  • have you check the webservers errorlog? and the magento-logs – Philipp Sander Jul 2 '19 at 8:07
  • magento - only has system log -- broken reference in ' notification ' – prabhakaran7 Jul 2 '19 at 8:09

i make mistake in index.php in root folder

i added some code that was not removed

this was just messing with the api calls from admin panel because it was corrupting json output.

This error can occur when there is a problem applying a filter to the current grid. It can be cleared by removing the records from the ui_bookmark table for your user.

If you aren't sure about your user id, run SELECT email, user_id FROM admin_user;.

Then run DELETE FROM ui_bookmark WHERE user_id = [USER ID]

This should clear the stored filter. However, it won't fix the underlying problem, so if you use the same filter, the error will occur again.

In the case I was investigating, it turned out that the data migration tool had migrated a product with no SKU. Giving it a value for SKU prevented the filter error.
