Error Types
Name | Docs |
|---|---|
| InvalidJustification | The given justification is invalid for the given header. |
| InvalidAuthoritySet | The authority set from the underlying header chain is invalid. |
| OldHeader | The header being imported is older than the best finalized header known to the pallet. |
| UnsupportedScheduledChange | The scheduled authority set change found in the header is unsupported by the pallet.This is the case for non-standard (e.g forced) authority set changes. |
| NotInitialized | The pallet is not yet initialized. |
| AlreadyInitialized | The pallet has already been initialized. |
| TooManyAuthoritiesInSet | Too many authorities in the set. |
| BridgeModule | Error generated by the `OwnedBridgeModule` trait. |
| InvalidAuthoritySetId | The `current_set_id` argument of the `submit_finality_proof_ex` doesn't matchthe id of the current set, known to the pallet. |
| FreeHeadersLimitExceded | The submitter wanted free execution, but we can't fit more free transactionsto the block. |
| BelowFreeHeaderInterval | The submitter wanted free execution, but the difference between best known andbundled header numbers is below the `FreeHeadersInterval`. |
| HeaderOverflowLimits | The header (and its finality) submission overflows hardcoded chain limits: sizeand/or weight are larger than expected. |
