This bug can be seen only with the latest version of har-export-trigger. With version 0.6.0. everything works just fine.

I guess you should launch geckodriver with argument --devtools and set option "devtools.toolbox.selectedTool" to "netmonitor" as mentioned [here](https://github.com/devtools-html/har-export-trigger/issues/8#issuecomment-368887624)

For me works the following code: ``` window.foo = HAR.triggerExport().then(harLog => { return(harLog); }); return window.foo; ``` Also don't forget to launch geckodriver with argument --devtools and set option "devtools.toolbox.selectedTool"...

Sorry for the long reply. Unfortunately, I can't help you with that since I'm not a JS programmer. These 2 lines of JS code are working pretty good with Python+Selenium....
