Hi everyone,   I got an application with an OData service. The app is in Mendix 9.12.4 and the OData seems to work fine, we get all our information nicely in our PowerBI environment. However I do have a lot of occurences of 2 errors in my logging, namely:   Exception occurred while serializing OData response. &  Exception occurred while serializing OData exception.   Stack traces are: org.eclipse.jetty.io.EofException at org.eclipse.jetty.io.ChannelEndPoint.flush(ChannelEndPoint.java:279) at org.eclipse.jetty.io.WriteFlusher.flush(WriteFlusher.java:422) at

And whether it is something that needs to be solved?
