On our Production environment we have the following error popping up in our Indicium logs once in a while. This is caused by an action of an end user, we presume. But how can we debug this error (based on Production logs - without using Debug mode)? I don't see any pointers in the below error message:

In the next version of Indicium when used with CloudWatch you can see the RequestPath to make this more clear. Like in the image below as an example - (note this is a different error but the structure will be the same).


That being said, we will also try to make the log message clearer when CloudWatch or Application Insights is not used.

@Dick van den Brink to clarify: so currently there is no way to debug this specific error as long as the reproduction steps are unknown?
