So far I have been able to convert HAR files without any issue, the gui app has been wonderful. While trying to convert a har covering the upload of a file I encountered the attached error. Searching google yielded zero results same with StackOverflow. Any suggestions on where to even begin debugging this?
How did you generate this HAR file?
It looks like your file is corrupted (invalid UTF-8 encoding).
I don’t know how, but indeed the file got corrupted. Remade the HAR and it works fine now. My first suspicion was that my coworker made the HAR on a different OS caused it, but could not replicate it.
