Failed to execute 'fetch' on 'Window': Failed to read the 'signal' property from 'RequestInit': Failed to convert value to 'AbortSignal'.

I have this issue on project https://gitlab.com/c1560/cryptofiscafacile

we use go compiled in wasm with go-resty.
When I add to the project pollyjs, i have this issue.

If I remove this line
https://github.com/ember-cli/ember-fetch/blob/master/assets/browser-fetch.js.t#L16 
The issue disappear.

I have set preferNative to true
