Hi all,

We have a customer who, after upgrading to 10.4.0.0-16295-CU18 from 10.3, is suddenly getting the above error on multiple elements. We think this is causing an impact on Automation scripts using these elements. I tried the workaround in the previous dojo post How to resolve System.Reflection.ReflectionTypeLoadException? - DataMiner Dojo to no avail.

Has anyone seen this error/able to explain it/know how to prevent it?

Full error:

All of the other elements experiencing this error also have xml serializers failing.
