Thanks Igor! By chance is the original .TS file available?

Thanks for the demo. The upload does seem to work for iOS (Success! is output at the end after some progress events). For android though, I am consistently "TypeError: Cannot set property 'NAMESPACE' of undefined" on the line:
const session = bghttp.session("image-upload");

Could you guys provide a similar code snippet that will work for android? Thanks!

What a version of nativescript-background-http did you use?
I have looked to releases of the plugin and seen fix for the issue in v.3.2.3

I'm on version 3.2.5 and unfortunately I'm still getting that error

I found the same issue in the nativescript-background-http repository (closed issues).
We will try to resolve this and let you know if there is any news.

Thanks!

@Vladlukhanin any update on this?
