Grapher redirects aren't working

[ikesau]

Problem

Grapher redirects are not working, and instead serving 404 pages.

Expected behaviour

They should redirect you to the desired different slug.

Example

https://ourworldindata.org/grapher/incidence-of-child-labour-in-the-united-states-1890-1930 should redirect to https://ourworldindata.org/grapher/incidence-of-child-labor-in-the-united-states-1890-1930 but it's not working.

Technical notes

• Site redirects are working

[ikesau]

A possible candidate might be this change to how we handled 404s in the Grapher worker. https://github.com/owid/owid-grapher/pull/3951/files

[ikesau]

Confirmed that be9c4e3 is the culprit, as https://f5a632ba.owid.pages.dev/ is the deploy where redirects stop working.

[ikesau]

Confirmed fixed by #3959

https://ourworldindata.org/grapher/incidence-of-child-labour-in-the-united-states-1890-1930 is redirecting correctly
