Why isn't my report loading when I use a lot of filters? (414 error)

Issue/Introduction

This is due to the URL string exceeding the string length limit.

We use a standard backend library component to parse web URIs, which has a hard upper limit on how long the string can be (15k).  When selecting many groups it's possible to exceed this limit and that's why we are seeing the error "414 Request-URI Too Large".  In some rare cases, it is possible to create a query that is too large, resulting in a report that either will not build or cannot be saved.  Most often, this is seen when selecting many or a combination of Perspective groups, Service items, or Accounts as filters within a report. 

There are several workarounds which can be attempted. 

• Try toggling between include to exclude when configuring filters to ensure that the lowest amount of filter options are selected which matches your reporting requirements. E.g. If you have 50 accounts and only want to report on 35, it is more efficient to exclude the unwanted 15 accounts rather than including the 35 accounts.
• If toggling between exclude/include does not help in your circumstance where the number of selected items in a filter is smaller than the inverse but still too large, try splitting up filters into smaller batches to reduce the resulting URL length.
