  • Just responding with a different bit of code and no explanation is not a good way to answer questions. Explain what column mismatch means. Winmerging the two definitions makes your answer no clearer.

  • HI @msquare, thanks for updating but for further clarity customer_online_columns is a mismatch with what directive - spinnner? These UI components are overly complicated and docs/useful examples are lacking so trying to work out how to work them is not easy! One day there'll be an "ah" moment but not there yet!

Check the parent and child class constructors, child class constructor may not be passing all the required arguments to will calling the parent constructor.
After making the constructor arguments same run php bin/magento setup:upgrade from CLI
