It's probably down to some enormous queries that we run to aggregate our data - CTE's nested to 6 levels with GROUPing etc. 2200 lines and 116K.

Is the JSON string length configurable?

    Hi,

    This error happens because one of the query may be very long. We are tracking this as SRP-4859 for now. This will be fixed for V 3.0 release.

    Thanks,
    Priya

    We had the JSON length issue in our Production .Net application and simply changed the config to get around it. No such ability with SQL Monitor?
