Broken Resizing For Native

[JamaicanSwede]

Type of issue

Bug

Description

Whilst updating Prebid from 8.32.0 → 8.52.0 we noticed the resizing functionality was broken for all of our native ads:

In the image, the height of the ad would previously be resized to 50px. However, now it's always static at 600px. We have the same resizing issue across all website that utilizes native.

We investigated the issue, and we concluded that there was a bug introduced in the version 8.52.0 of Prebid. In this version, in the file secureCreatives, a new function was introduced: getResizer. See: https://github.com/prebid/Prebid.js/compare/8.32.0...8.52.0?diff=unified&w=#diff-46212f953e474e4bccd13c2ca036cd27698fcd13fdba21276129f3646d9e3561R72-R79

The function expects two arguments, however not all invokers have been updated accordingly, as in the case of the native invoker handleNativeMessage (located in the same file)

Consequently, the adId argument is now instead the bidResponse object, which subsequently breaks the resizing functionality.

Suggested solution

We tried setting the right arguments in the invoker: handleNativeMessage(data, adObject, {resizeFn: getResizer(data.adId, adObject)}) and the resizing started to function as expected again.

Platform details

Prebid version: 8.52.0
