Complete ad skip reasons
Skip reason Description
NEW_CREATIVE The ad has not been transcoded yet. This occurs when MediaTailor encounters a new ad creative that requires transcoding before insertion.
PROFILE_NOT_FOUND The MediaConvert transcode profile associated with the session's configuration does not exist, preventing ad preparation.
TRANSCODE_ERROR The ad transcode process encountered an error and failed to complete.
TRANSCODE_IN_PROGRESS The ad transcode is still in progress and not yet ready for insertion.
INTERNAL_ERROR An internal MediaTailor error occurred while handling the ad, preventing insertion.
AVAIL_DURATION_EXCEEDED The ad does not fit within the remaining duration of the ad break.
LEFTOVER_AVAIL_EXCEEDED_THRESHOLD The cumulative duration of all ads that could have been inserted does not meet the personalization threshold configured for the session.
VAST_PARSING_ERROR The VAST response from the ad decision server contains errors or is malformed.
ADS_TIMEOUT The ad decision server did not respond within the configured timeout period.
MEDIA_FILE_UNAVAILABLE The ad media files specified in the VAST response are not accessible.
SESSION_INITIALIZATION_FAILED The MediaTailor session failed to initialize properly, often due to incorrect session variables.
EARLY_CUE_IN The ad break ended earlier than expected due to an early cue-in signal, preventing the ad from being fully inserted.
NO_VARIANT_MATCH The ad creative does not have a variant that matches the content stream's encoding parameters (bitrate, resolution, codec).
NO_MODEL_CREATIVE_MATCH The ad creative does not match the expected model or format requirements for the current playback configuration.
REJECTED_REPLICA_VAST The VAST response was rejected due to replica or duplicate content detection policies.
INVALID_VAST_WRAPPER_AD The VAST wrapper ad contains invalid or malformed wrapper elements that prevent successful ad insertion.
IMPORT_ERROR An error occurred during the ad import process, preventing the ad from being processed for insertion.
