I got this error while trying to make category "is_anchor" yes or no. If i save category without changing this "is_anchor" attribute then it works fine.
I have migrated the store from Magento 18.104.22.168 to Magento 2.4. I have done migration successfully.
I have tried below steps, still facing same error,
- truncate the url_rewrite and then reindex URLs for category and products.
- I have installed this https://github.com/olegkoval/magento2-regenerate_url_rewrites extension and regenates URLs. Still it giving me same error.
Please check below screenshots,
Please let me know if you guys have proper solution.
