Hi, After Magento 2.3 to 2.4 upgrade, The admin data grid not loading any data. I cannot be able to view Sales, Catalog, Customers etc. I have tried so many fixes from the forum does not help.
How do I know which Extension is creating any issues ? I am running PHP7.4 on a CentOS 8.
I have disabled the Elasticsearch also.
Open the same url in Google Chrome and then open the console tab via inspect window or by ctrl + shift + i and then search for the error.
There is some issue in the js.
