You tried to upload a glTF file without embedded assets. It should be inside a folder with other files. Drop that folder onto the dropzone to create a single file that can be used.
Ulijaribu kupakia faili la Umbizo la Usambazaji wa GL (glTF) bila faili zilizoingia. Inapaswa kuwa ndani ya folda na mafaili mengine. Weka folda hilo kwenye eneo la kushuka ili kuunda faili moja ambalo linaweza kutumika.
