• i stripped the access tokens and left a note that's come through in the post just as <> but was < access token removed for obvious reasons >

Additional note: if you don't ask for the breakdown the result parses fine but i need to link_url_asset

[nvlgregory]

okay so the reason the SDK falls over on this is a change in the API structure on link_url_asset from String to an Object containing website_url and id. The SDK needs to be updated to handle this change. Please, for the next version fix this

thanks for reporting this. the breakdown link_url_asset was introduced and by default all the breakdowns were set to String type. it's a gap to fix all the non-string type breakdowns. we'll introduce the new type AdAssetLinkURL and map this breakdown's output to this type.
