EXTRINSIC_NOT_FOUND

No such extrinsic. Asked by hash, it may not be seen yet: the problem then carries indexed_through_height (the newest finalized block the index has processed) and details, an ExtrinsicStatus with status not_seen; a later retry may find it. Check the id or hash; for a hash just submitted, retry after a few blocks.

Status:

404

Retry unchanged:

no
