Hi Yuri,
it may also be depending on where you are loading these odata models.
1) are your url and url2 valid URLs?
2) are you doing this on the Component.js file during the init function? (based on your JS code)
have you tried loading them from the manifest.json file ?
check out this blog and see if this helps you.
