the CORS battle.

Hi there!
I’m trying to fetch a CSV that has been uploaded to wordpress, to make it really easy for the client to upload a new one when needed that will update the data on the embedded observable graphics.

I’ve fiddled with the headers on the wordpress side to no avail.

(in the meantime I’ve found this little cors tester tool very handy)

I still keep getting the CORS error:

Access to fetch at ‘https://labusqueda.eaaf.org.ar/wp-content/uploads/2025/04/Consolidado_Micrositio_EAAFIdentificados_DATASET.csv’ from origin ‘https://rusosnith.static.observableusercontent.com’ has been blocked by CORS policy: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.

Any clue?

You were only testing your homepage, not the actual file URL: CORS Tester - Test a URL for valid CORS headers

I’m afraid this question is likely better suited for a Plesk or Wordpress forum.
