EPiServer.Commerce.UI.CustomerService Issue



We just upgraded to the commerce version 13.27.0 and started getting the below error: If I delete the "" from  modules > _protected website works fine but Commerce UI does not work in the backend (as expected) but when adding the file back - error back again. Appreciate any help.

If you could catch the exception somehow, that would be great. In some IDEs in you can set a breakpoint in decompiled code - that would help here. If you can do so, maybe you can use the "Evaluate expression" functionality of the IDE to run the code that fails in order to find the exception.

Anyway, I think it's likely that the exception is about some dependency. You can at least try the following things:

  • Clear bin and obj folders and then rebuild
  • Check if all binding redirects are correct - It's not unlikely that you reference a DLL of a certain version but maybe you have the wrong binding redirect or you're missing a binding redirect for that DLL

Apparently you are seeing bug COM-12602, which was fixed in 13.28 (better handling of dynamic type loading). Please upgrade (best to 13.33)
