Describe the bug
We see the VAST content in the adm field of some demands contain the single quote character rather than the escape double quotes (\") that cause the VAST_REGEX cannot detect the VAST content in adm field. For example:
{ "id": "fa3a1f74-e945-432c-b16c-d924506e7771", "seatbid": [ { "bid": [ { "adm": "<VAST version='2.0'>..." } ], "seat": "1" } ], "cur": "USD" }
Therefore, the adUnitIdentifierType is assigned to the value of AdFormat.INTERSTITIAL when checking in file PrebidMobile/PrebidMobile-core/src/main/java/org/prebid/mobile/rendering/bidding/display/InterstitialController.java --> adUnitIdentifierType = bidResponse.isVideo() ? AdFormat.VAST : AdFormat.INTERSTITIAL;
The current regex to check if the content is vast:
VAST_REGEX = "<VAST\\s.*version\\s*=\\s*\".*\"(\\s.*|)?>";
Is it correct if we add the single quotes to the above regex? Change it to
VAST_REGEX = "<VAST\\s.*version\\s*=\\s*[\"'].*[\"'](\\s.*|)?>";
