}
Expand description
A error raised during validation of the candidate.
Variants§
Preparation(PrepareError)
Deterministic preparation issue. In practice, most of the problems should be caught by prechecking, so this may be a sign of internal conditions.
In principle if preparation of the WASM
fails, the current candidate cannot be the
reason for that. So we can’t say whether it is invalid or not. In addition, with
pre-checking enabled only valid runtimes should ever get enacted, so we can be
reasonably sure that this is some local problem on the current node. However, as this
particular error seems to indicate a deterministic error, we raise a warning.
Invalid(InvalidCandidate)
The error was raised because the candidate is invalid. Should vote against.
PossiblyInvalid(PossiblyInvalidError)
Possibly transient issue that may resolve after retries. Should vote against when retries fail.
Internal(InternalValidationError)
Preparation or execution issue caused by an internal condition. Should not vote against.
ExecutionDeadline
The execution deadline of allowed_ancestry_len + 1 has been reached. Jobs like backing have a limited time to execute. Once the deadline is reached, the current candidate cannot be backed, regardless of its validity.
