VAST Error Code Troubleshooting Matrix
Error Code Fatal? Definition Possible Causes
100 Yes XML parsing error. VAST supplied in adm is not a valid XML document. URL supplied in nurl does not resolve to a valid XML document. Nurl only: Server did not respond with VAST, or at all when player called the nurl. Perhaps a CORS issue
101 Yes VAST schema validation error The VAST validates as XML, but does not validate per the VAST schema (i.e. there are missing mandatory elements or attributes, or combinations of elements/attributes that are not permissible). Some possible reasons for invalidity: InLine and Wrapper both present. AdTagURI missing in Wrapper element. Duration missing. Missing Ad node or MediaFile node. Offset attribute on Progress event is missing or not a valid value.
102 Yes VAST version of response not supported. Bidder did not respect the VAST version(s) listed in the bid request. Exchange is sending wrong VAST version(s) in bid request. VAST does not contain version (this could also be considered a schema validation issue)
200 Maybe Trafficking error. Video player received an ad type that it was not expecting and/or cannot display. Player wanted Skippable Linear, but got back Linear. Player wanted Linear, but got back Skippable Linear. For Skippable Linear, skipoffset doesn’t meet publisher expectations. Bidder did not respect the skippability/skipoffset in the bid request. Exchange is sending wrong skippability/skipoffset in the bid request. Potentially any of the reasons in 201-203
201 Maybe Video player expecting different linearity. Bidder did not respect the linearity in the bid request. Exchange is sending wrong linearity in the bid request
202 Maybe Video player expecting different duration. Bidder did not respect the duration in the bid request. Exchange is sending wrong duration in the bid request
203 Maybe Video player expecting different size. No MediaFile is available with dimensions that are matching for the device (i.e. mobile devices that cannot play full HD). No MediaFile is available with an acceptable bitrate. Bidder did not respect maxbitrate. Exchange is not sending maxbitrate
