I have also received this same error with the same Tech details while trying to upgrade from 4.9.3.SP1 - 4.10.1
I have no modifications to the store.
Has anyone found a solution.
I have managed to upgrade my store, in 4.9.3.SP1 I installed the cs-cart store locator add-on and did not fill in any information in the add-on, then in administration/upgrade center I proceeded with the upgrade to 4.10.1 and was successful.
Note: In 4.9.3.SP1 the cs-cart store locator add-on was not previously installed.
During the upgrade to 4.10.1 the cs-cart store locator add-on is automatically replaced by the new cs-cart Stores and pickup points add-on.
I am not sure if this is a bug in the upgrade or was just a problem with my upgrade process.
I was looking at waiting until Monday so this solution helped
