Chrome HAR File size limitation

Environment

Problem at hand

For debugging purpose, I log network traffic and save it as a HAR file. When the resulting HAR file is large ( > ~12Mb ) it's content is truncated, resulting an Invalid JSON object.

Just strange behavior on my Chrome 80 on Ubuntu: HAR file wrote fast first 8MB (in this case file truncated), after that file continue writing very slow (~1MB in minute) and go to 75MB (in my case) in hour or more.

This may not be the solution for everyone, but I've just checked that Opera v56 allows HAR file that contains a JSON object that is 1.1MB.

Chrome and Firefox both truncated the same JSON data object.

However that overall HAR output file from Opera somehow also accumulated to a very large size of 221MB.

I'm not sure why you are seeing HAR file truncation but you could try using HttpWatch:

https://www.httpwatch.com

It does not have a limit on the size of the output HAR file and can also record in a more compact HWL file format.
