@davidosomething thanks for reporting it. Can you provide us with your operations system name and pwmetrics version. Also do you run it in a terminal or something?

[paulirish]

Thanks. It's an upstream bug in Lighthouse I just filed there: GoogleChrome/lighthouse#1534

[davidosomething]

thanks @paulirish

[pedro93]

@davidosomething Can you check if this bug is still reproducible using the master branch version of pwmetrics?

[davidosomething]

As part of the work in progress #71 I've been running pwmetrics with the multiple run options and caught this exception.
