Prebid.js: Audience Network - If Native Format is passed ANY size should work

[jfb716]

Type of issue

Bug

Description

In the adapter you have 300x250 and 320x50 as the only accepted sizes (which is correct), but if a publisher is running native we should accept any size since it'll be native on their site and not a standard IAB size like 300x250 and 320x50. You actually wouldn't want to run native through those sizes since that wouldn't be true native.

Steps to reproduce

This configuration doesn't fire the AN endpoint but it should since i'm passing 'native' as the format:

var adUnits = [{
code: 'div-gpt-ad-1',
sizes: [[728, 90]],
bids: [{
bidder: 'audienceNetwork',
params: {
placementId: '154187914959322_519264628451647',
format: 'native'
}
}]
}];

Test page

I have this live here: https://jfb716.github.io/

If you change the adUnit size to 300x250 or 320x50 you see the bid request triggers.

Expected results

If 'native' is passed in the adUnit configs, we should not do a size check since native can be any size the publisher wishes.

Actual results

The endpoint doesn't trigger, doesn't get past the invalid size check.

Platform details

N/A - happening across the board, not platform specific

@lovell maybe native needs an exception here, like video does? https://github.com/prebid/Prebid.js/blob/master/modules/audienceNetworkBidAdapter.js#L29

Hello, thanks for reporting this problem, I plan to submit a PR to address this in the next couple of days.

[snapwich]

@lovell would you mind looking at #2199 while you're at it as well to see if it's an issue? Thanks.

[lovell]

PR for this at #2203.

Hey @lovell technically the Fullwidth should only work when configured for a 300x250. We wouldn't ever want this to server through a 320x50 because it would look really bad and cause problems on a publishers site. Native should work for any and all sizes, but fullwidth i would restrict to 300x250. Let me know what you think.

[lovell]

@jfb716 That's a good question. The fullwidth format "extends beyond the 300x250 frame" so perhaps it might make sense to future-proof and remove the existing size limitation here also, even if most ads will still be using IAB dimensions for now.

@lovell I spoke to the team and the consensus is to restrict fullwidth to only 300x250 if possible (messaged you on facebook). Let me know if that's feasible, thanks for your help!

Hey @lovell! We just realized this is only in the 1.0+ library, is there any way to get it into the pre 1.0 library as well? Thanks!
