Lighthouse: Unable to run generate report on localhost

Question

As the title says I'm trying to generate a report for my nuxt app served locally. If I generate the report via DevTools it takes an extremely long time and gives me exceptionally bad scoring(compared to generating the report on the same site deployed).

If I try using the lighthouse extension the "Generate report" button is disabled.

Am I going about this wrong or is there any way to locally generate valid reports?

Thanks in advance.
