Why is the browser crashing when trying to export my report in BUI?

One of the causes of this behavior is the data set for the exported report being too large to successfully process. If this call to the server takes longer than 30 seconds (due to the large JSON request payload) the read request will time out. As such, BUI is not designed to handle this type of payload. If you suspect the data set in your report is too large to be exported in BUI, we recommend making use of other features in .NET like published and scheduled reports that are specifically designed to handle this type of payload.
