E-PIA: Intermittently Users Get Error "Unable to get document: HTTP 400 - Bad Request" when Navigating on PIA Pages (Doc ID 2948262.1)

Last updated on JULY 11, 2023

Applies to:

PeopleSoft Enterprise PT PeopleTools - Version 8.59 and later
Information in this document applies to any platform.


Site is seeing quite a number of "Unable to get document: HTTP 400 - Bad Request" messages in the PIA_sevlets0.log.0 logs.
Users navigate to pages that work most of the time, but are presented with the error shown below instead of the page.
Having users clear cache and cookies usually resolves the problem, but lately the errors occur within a login session.
So they'll log out, clear cache and cookies, log back in, be ok for half an hour, and then start getting the 400 errors again.


Steps to replicate:

1. Log into PIA, navigate to various pages, and observe the error shown above.
