invalid link for opengraph-image when using mode as-needed and prefixes

[sss-Mihail-sss]

Description

The og:image link is incorrectly generated when using language prefixes from the next-intl package. For Spanish (/es), the link is formed as /es/opengraph-image, but it should be /spain/opengraph-image. This causes a 404 error when the link is accessed.

Verifications

• I've verified that the problem I'm experiencing isn't covered in the docs.
• I've searched for similar, existing issues on GitHub and Stack Overflow.
• I've compared my app to a working example to look for differences.

Reproduction description

Steps to Reproduce:

1. Open the project with the es language using this link: localhost:3001/spain.
2. Open the DevTools or any extension to check the SEO metadata.
3. Observe the og:image link.
4. When the link is opened, it changes to /es/spain and results in a 404 error.

Actual Behavior:

For Spanish, the link to og image /es/opengraph-image when opened redirects to /spain/es/opengraph-image, resulting in a 404 error.

Examples:

1. Default language (working) :

   • Open Graph Meta
     
   • Open Link
     

2. Spanish Language (not working):

   • Open Graph Meta
     
   • Open Link
     

Expected behaviour

For Spanish, link to opengraph-image should be /spain/opengraph-image

Example for correct link /spain/opengraph-image

Thanks for noticing! I've adapted the example in #1658 to work correctly and have also added a paragraph to the docs about this case. Let me know if this helps!
