When investigating Sonatype product issues regarding the user interface (UI), we may sometimes request a HAR file in order to troubleshoot the reported issue further. This is needed to investigate the network requests being made from the UI when the problem you are experiencing is occurring.
HAR (HTTP Archive) is a file format (JSON) used by several HTTP session tools to export the captured data (HTTP requests and responses).
Note: A HAR file must always be captured on the UI page where you are experiencing the reported issue.
This article details how to capture a HAR file for each of our currently supported browsers.
