Note that although this question references wikidata, it is really a javascript fetch question. Also, this is not the wikidata api. I’m just trying to load a simple page from a url.

I want to access wikidata using a QID. My code generates a URL like

https://www.wikidata.org/wiki/Q111943988

which works from the browser (try it). But when I try to get it by calling fetch from the js script in my web page I get errors. Here is my code …

      const wdataResp = await fetch("https://www.wikidata.org/wiki/Q111943988",
        {method: "GET",
         mode: 'no-cors',
         headers: {
          'Content-Type': 'application/json',
           'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) ' +
                         'AppleWebKit/537.36 (KHTML, like Gecko) ' +
                         'Chrome/131.0.0.0 Safari/537.36'}
        });

It gives this response …

wdataResp: Response
  body: null
  bodyUsed: false
  headers: <weird set of functions here>
  ok:false
  redirected:false
  status:0
  statusText:""
  type:"opaque"
  url:""

Note the ok:false. I don’t think this is a cors problem. I got cors errors from this code and the mode: 'no-cors'
fixed it.

Can someone give me ideas on how to fix this? Thanks in advance.
