When encountering an issue, there is sometimes a need of deeper data to be able to analyse the issue root cause. The HAR file (HTML archive) is a way how to analyse software errors. It is a record of operations that happen in Google Chrome when a user is performing what appears to be a problematic action.
Getting HAR file
Below are two options how to record HAR file.
MAC Os users:
Windows Google Chrome users:
In Chrome, go to the page where you want to record the HAR file:
- Open Developer Tools (Inspect)
- Click the Chrome menu, three dots in the upper right corner of the browser window ⋮
- Select Mote tools> Developer tools for developers.
- Start capturing your screen via this free Google Chrome plugin - link HERE
- Click the Network tab.
- Check the Preserve log at the top.
- A red circle appears at the top left of the Network tab. This means that the recording started. If the circle is black, click the black circle to start recording activity in the browser.
- Refresh the page 
(F5 / refresh) and repeat the problem while recording is active.
- After the problem reproduces successfully, right-click any row of the activity pane and select Save as a HAR with content.
