Hi,

I am using mitmproxy v3.0.4 and generating a HAR file using the following:

`mitmdump -n -r dumpfile -s "har_dump.py" --set hardump="ooo.har"`

On opening `ooo.har` in any online HAR viewer, I see nothing, whereas there are entries in the HAR file.  
On difference which I see between HAR files that show up correctly, is the absence of the `pages` key.  
It is obvious that the `har_dump.py` has not chosen to set the `pages` key, any particular reason for that ? I can open an issue on Github, and possibly try to fix that.

As a workaround for that I tried stubbing some generic data under `pages` in `har_dump.py`, but still the HAR viewer shows it empty, maybe I have messed some timestamps etc.

But, anyways, what can be done in this case ?

Thanks

It works for me to open the generated HAR files by drag-and-drop to Chrome’s web developer “network” tab, as noted at [https://stackoverflow.com/a/47164935/507544](https://stackoverflow.com/a/47164935/507544).

Can you give an example `ooo.har` file, and an example online HAR viewer?
