[Bug]: console shows PATCH request with 409 Conflict result after cache clear (160001)

[lmeurs]

What happened?

The first time a page with our OneSignal implementation is loaded after clearing browser cache + cookies, the console shows a 409 Conflict error:

OneSignalApiBase.js:67 PATCH https://onesignal.com/api/v1/apps/800f295a-a6b2-49c9-9fb1-2555e1e8df91/users/by/onesignal_id/e99029ac-39b1-459c-9409-0b5c48cb78ab/identity 409

The URL shows the following message:

{"errors":[{"title":"No aliases found for oneSignalID e99029ac-39b1-459c-9409-0b5c48cb78ab"}]}

Our test OneSignal account only contains 4 subscriptions, none of them indeed has OneSignal ID e99029ac-39b1-459c-9409-0b5c48cb78ab. Sidenotes:

1. The error no longer occurs after reloading the page
2. The OneSignal ID changes each time when reproducing this
