[xeokit plugin ifcLoader]: getXKT error : null

[Jongonzale]

Hi,

I'm starting with the SDK, and when I execute one of the examples it has, or a code done by me following the documentation, I always receive the message of that error, and the page it charges doesn`t have any model in it, only the blue page. Why is that happening? What's the solution? Thanks

Sorry, we're not able to reproduce this issue. If it's still happening, if you can some steps to reproduce we'll re-open a take a look.

Hi, i reproduce this issue when loading a IFC file.

I just check when u load a Blob file using axios or fetch, and you try to use it as an URL ( using URL.createObjectURL ) the loader do something... weird to me

When the ifcLoader try to request the src url, it add a queryParameter

When i paused the script at that point and i delete the query param, it works

Update:

I found the line that adds this params is the function _cacheBusterURL

Package: @xeokit_xeokit-sdk.js function:

getIFC(src, ok, error2) { 
 src = this._cacheBusterURL(src);

Solution:

When i create the loader this fix the problem to me

myLoader.dataSource.cacheBuster = false

Thanks for digging into this - we'll make that cacheBuster option false by default
