Changes

• Use file-loader to import the file upload worker script path.

Tests

• Manually tested.

We have existing integration tests that test file uploads using a NativeScript Android application. Not sure why this was not failing. I need to discuss with QA team.

Is the root cause of this issue known? Why did using file-loader fix this issue?

[thomasconner]

You need to pass a file path to create a worker. There did not exist a file at the path provided because the project is bundled with Webpack. File-loader includes the file correctly so that the file is loaded when provided the file path.

Ok, sounds like maybe there is something different in the configuration for the integrated tests. Would be good to know how that was passing, but other than that LGTM.
