Troubleshooting¶
Error codes¶
To reduce code size, on-chain errors only output codes. Here’s what they mean:
Ledger errors
L0: Input constraint
L1: Output constraint
L2: Missing datum
L3: Wrong validation interval
L4: Missing signature
L5: Spent value not OK
L6: Produced value not OK
L7: Public key output not spent
L8: Script output not spent
L9: Value minted not OK
La: MustPayToPubKey
Lb: MustPayToOtherScript
Lc: MustHashDatum
Ld: checkScriptContext failed
Le: Can't find any continuing outputs
Lf: Can't get any continuing outputs
Lg: Can't get validator and datum hashes
Lh: Can't get currency symbol of the current validator script
Li: DecodingError
State machine errors
S0: Can't find validation input
S1: State transition invalid - checks failed
S2: Thread token not found
S3: Non-zero value allocated in final state
S4: State transition invalid - constraints not satisfied by ScriptContext
S5: State transition invalid - constraints not satisfied by ScriptContext
S6: State transition invalid - input is not a valid transition at the current state
S7: Value minted different from expected
S8: Pending transaction does not spend the designated transaction output
Currency errors
C0: Value minted different from expected
C1: Pending transaction does not spend the designated transaction output
