Lighthouse says "Manifest start URL is not valid"

[ned-bs]

Hi there,
I couldn't find a document where to start with this plugin.
There are many documents around, most of them are way too technical but there is none to lead how to start.

1. I installed and activated plugin
2. Set shortname - General Settings
3. Offline browsing checked - Reading Settings

Then tested if it works via chrome browser.
Right click - Inspect- Lighthouse-Analyze page load

I got error message like below.
Could you please give simple, step by step installation guide.

PWA - INSTALLABLE
Web app manifest or service worker do not meet the installability requirements 1 reason

Failure reason -- Manifest start URL is not valid

I also have error for "Manifest doesn't have a maskable icon" but find documentation about it.

What's the URL of your site? I need to know what the start_url is set as.

I also have error for "Manifest doesn't have a maskable icon" but find documentation about it.

Good question. This is set in the Customizer (/wp-admin/customize.php), specifically in the Site Identity panel. There is #915 for eliminating the reliance on the Customizer.

I see you cross-posted your question on the support forum: https://wordpress.org/support/topic/how-to-use-it-72/

Closing that topic as a duplicate.

Hi Weston,
Thanks for reply. Here is my website.
I am trying to understand how I should make it right.

I have added start url in to a file called site.webmanifest.
It it right approach?

@ned-bs You don't actually need to add a web manifest yourself. The plugin does this automatically. You can see it doing so as follows:

<link rel="manifest" href="https://www.laptop.com.tr/wp-json/wp/v2/web-app-manifest">

That manifest has the start_url set to https://www.laptop.com.tr/ which seems correct.
