Cannot covert a Charles proxy HAR file into a script

[Ardesco]

Looks like the HAR convertor does not work with har files saved from Charles proxy.

Added an example HTTP Archive and the script created by running the following command (both files in the attached zip):

k6 convert example.har -O example.js

example.zip

Confirmed, this is a bug - seems like the k6 HAR converter assumes that there's a pages key in the HAR file. This makes sense for HAR files recorded in browsers, but proxies would have no idea what to put there so they don't include it. And regardless, the spec says that pages is optional, so we shouldn't depend on it...

Until we fix this (probably together with the rest of the several HAR converter improvement we want to make and issues we have to fix), you can work around the problem by manually editing the .har file and inserting a dummy page with "" for ID, like this:

{
  "log": {
    "version": "1.2",
    "creator": {
      "name": "Charles Proxy",
      "version": "4.2.7"
    },
    "pages": [
      {
        "id": "",
        "title": "dummy"
      }
    ],
    "entries": [
      /* ... */
    ]
  }
}

Workaround works perfectly, thanks :)

Received another issue about this (non-Charles Proxy related), so I think we should fix it before 1.0. The quick fix should be easy enough, we can just officially use the minor hack I proposed as a workaround - inserting a placeholder element in pages if it's empty... We're going to majorly refactor (for this among other reasons) the HAR converter post 1.0, so we'll properly deal with it when that happens, but the quick fix should suffice until then.
