When bugs occur on Filestage, it is sometimes difficult for our developers to remotely identify any process quickly, as there are often many individual local factors involved. Sometimes when you face a bug, we will ask you to assist our developers in diagnosing the issue by producing an HAR file.

An HAR file (HTTP archive) shows the sequence of redirections that occur during a login transaction. It is an excellent tool for troubleshooting authentication problems, as it can detect where things get stuck. An HAR file is a JSON-formatted protocol of the interactions of a Web browser with a Web server. If authentication does not work as expected, you can generate and analyze HAR files to find problems. Including an HAR file in your support requests can speed up the troubleshooting process.
