Read this off the ad unit please

Here's an example

Prebid.js/modules/ttdBidAdapter.js

Line 198 in 6f4fb5b

const pos = parseInt(utils.deepAccess(bid, 'mediaTypes.banner.pos'));

Hello, I have updated the code to read the data off the adunit. However I seem to have an issue with one of the tests unrelated to the change, updating the branch with the current master did not seem to help. Do you have an idea what is the problem maybe? Thank you

Rerunning CircleCI. There is currently a flaky test that is popping up more often the last several days

Appears to still not be read off mediatypes.banner.pos

[wsusrasp]

@patmmccann It seems I have misunderstood due to naming collision - the pos that I am reading off the bid params is not the same as adunit's pos. The one here is our custom param for determining the position of adunit with the same name if they are embedded multiple times. It is impossible for me to set that parameter elsewhere and mixing it with mediaTypes pos would later yield incorrect results when generating reports, since it takes different values than we expect. How should I proceed in this case?

[patmmccann]

interesting; the 'pos' is an extremely well understood field by most rtb participants; perhaps you'll want to reconsider the name to avoid the collision and the resulting confusion?

[wsusrasp]

Sadly we are already using this value in multiple applications on our side and refactoring it will not be easy

[patmmccann]

How about you copy it to pos on the endpoint payload but your publisher facing configuration has a better choice of name?

[patmmccann]

Sequence seems like a candidate parameter name

[wsusrasp]

That sounds reasonable, I'll update the PR shortly. Thanks
