Hello, 

We have had the display error shown in appended screenshot appear randomly, at differents parts of workflows that worked fine on the previous run through. This has happened with varying frequency on multiple applications under theme cosmos.

Once the error appears, the only way to make it leave is to refresh the navigator and then the case, after doing so we are able to continue with the case as normal. Sometimes the refresh is not sufficient and we have to log off and on before being able to continue as normal. Tracer is no help as it just indicates the same thing with no context for what started the error, logs do not show anything wrong and as you can see in the image below stacktrace is empty.

Are there any existing solutions for this?
