I'm trying to extract some portion of the file using file/{:id}/content API with range attribute in the header, but it is giving me CORS error.

  Hi there,

  This information should give you more details on how to address the CORS issue, which I'm guessing is related to making the request from JavaScript?

  Hi Jon,

  Yeah, I was trying to make a range request in javascript.

  I figured out after some trial and error that the BOX API was expecting range: bytes={start}-{end} in the request header. But the API reference documentation did not specify that it requires bytes= in the range attribute. Below is the working code, I was not including bytes= earlier and that was causing the issue.

  const response = await fetch(`https://api.box.com/2.0/files/${id}/content`, {

          headers: {

              "Authorization": `Bearer ${access_token}`,

              'range': `bytes=${start}-${end}`

          }, 

      });

   

  Thanks,

  Bhaumik
