Failed To Upload Zip File "model Upload Failed. (reason: 100)"

I'm trying to upload zip file through API, the zip file contains a model with texture ( result.obj, result.obj.mtl, 0.png )
but I got this response
{"result":"failure","reason":"Model Upload Failed. (Reason: 100)"}' }

any help ?

This may not be the cause of this failure (though it could be, due to the presence of the unrecognized obj.mtl file), but OBJ with texture will not work - you need to use DAE, WRL or X3D format for color or texture

Hi,
If anyone finds this useful:

If this is an upload with the ruby gem lib, I found that reason: 100 is a farraday http lib error- because the JSON error response that's returned from the API in unparsable.
