Netlify Lighthouse plugin stopped working, Summary for path '/': undefined

Support
1

Hi,

We’ve started using Netlify for our client about 6 months ago, somewhere since the beginning we had the netlify-lighthouse plugin enabled in our project (on netlify.toml, without any custom configurations) and it was working fine.

At some point it suddenly stopped working (I believe it stopped working a few months ago).

Our builds are showing the following result of the plugin:

@netlify/plugin-lighthouse ran successfully
Summary for path '/': undefined

When I retrigger a build by clicking “Clear cache and retry with latest branch commit” I’m getting a different result:

@netlify/plugin-lighthouse ran successfully
Error testing '/': Lighthouse was unable to reliably load the page you requested. Make sure you are testing the correct URL and that the server is properly responding to all requests. (Status code: 404)

I went to check this forum to see if other people experience the same issue, I’ve found a few topics but none of them seem to have a solution or a fix.

This one looks more or less similar:

I also noticed the Github page doesn’t accept any issues/bugs at the moment: “Contributions and bug reports to the project are not being accepted at this time.”

I’ve tried setting all different kinds of configurations, also tried removing the plugin from our netlify.toml and installed it through the Netlify UI, but nothing seems to fix the issue.

Hope someone here is able to help me.

Could you share the site name?

I’ve create a sample site to share with you, it was also a good test to see if it happens there as well, and it does:

Site:

Deploy logs:

As you can see on the logs:
Lighthouse was unable to reliably load the page you requested. Make sure you are testing the correct URL and that the server is properly responding to all requests. (Status code: 404)

I’ve replied with the sitename above, not sure if you got a notification, because I wasn’t sure now if I clicked reply last time.

Sorry for the delay on this one. I’ve responded to this in the helpdesk.
