What happened?
When trying to run an audit, received an error and was unable produce an audit. Sometimes and audit would work, but only the PWA audit report was displayed/created.
What did you expect?
Expected to generate a full audit report. All audit settings selected. Only the PWA section was generated sometimes. Issues replicated in incognito.
What have you tried?
Using latest chrome browser, restarted browser, removed/re-installed extension, and allowed incognito extension use.
