What does this warning mean? arraybuffer being served with Content-Type:undefined

Hrishi_A · September 2, 2018, 11:15am

WARNING: responseType: arraybuffer being served with Content-Type: image/vnd-ms.dds
playcanvas-stable.min.js:37:554

or

WARNING: responseType: arraybuffer being served with Content-Type: undefined playcanvas-stable.min.js:37:554

I get these warnings in the console depending on the server on which the site is uploaded.
Does not seem to affect the site but I am curious about what it means.

PlayCanvas expects the content type image/dds, but your web server is setting image/vnd-ms.dds or none at all.

Here is the list which content types a web server should set:

github.com

playcanvas/engine/blob/master/src/net/http.js#L16


 * @description Create a new Http instance. By default, a PlayCanvas application creates an instance of this
 * object at `pc.http`.
 */
var Http = function Http() {
};


Http.ContentType = {
    FORM_URLENCODED: "application/x-www-form-urlencoded",
    GIF: "image/gif",
    JPEG: "image/jpeg",
    DDS: "image/dds",
    JSON: "application/json",
    PNG: "image/png",
    TEXT: "text/plain",
    XML: "application/xml",
    WAV: "audio/x-wav",
    OGG: "audio/ogg",
    MP3: "audio/mpeg",
    MP4: "audio/mp4",
    AAC: "audio/aac",
    BIN: "application/octet-stream"

To fix your web server, you can go to C:\xampp\apache\conf\mime.types and add this line:

image/dds dds

Or maybe your mime.types file already has the line image/vnd-ms.dds dds, then you need to fix that one.
