codes d'erreur detransaction?

Un échec aléatoire Exempletransaction surtzscan.io ne fournitpas de code d'erreur spécifique .Il a étéinjectépar unnœudinconnu sans accès à sa sortieterminale.

Y a-t-il unmoyen de retracer comment l'erreur a émergéet que celane figuretout simplementpas dans TZScan?

Transaction error codes?

A random failed example transaction on tzscan.io does not provide a specific error code. It has been injected by an unknown node without access to its terminal output.

Is there a way to retrace how the error emerged and is this simply not shown in tzscan?

Échec destransactions doivent être détectéeset obtenir un code d'erreur renvoyé dans lapriorité (RPC). Pour que cettetransaction ait étéinjectée,indiquez unbug ou unemauvaisemanipulation d'erreurs dans unportefeuille. Ilesttrèsfacile de voirpourquoi cettetransaction a échoué. Il aessayé d'envoyer le solde completet n'aurapas assez defondspour couvrir labrûlure.

Vouspouvez utiliser le RPCpour obtenir lesmétadonnées. Dans cetexemple,vous vérifieriez les ophases auniveau 296452 . L'ophash quenous souhaitons de votre lien d'origineest onuebjvrbaxtn4ik8kfzc4a8xtkfkyafxine698slm3mtnimdus

Lesinformations complètes sur lebloc sont accessibles à

https://rpc.tezrpc.me/chains/main/blocks/296452

Pourfaciliter,nouspouvonsfiltrer l'opération spécifique quenousintéressons. Les opérations sontindexéespar 2 valeurs. Lepremierindex seratoujours 3pour les opérationseffectuées àpartir d'unportefeuille.

La deuxième opération HASH (Index 1) Voici celle quinousintéresse,nous allons donctrouver votre ophash à l'emplacement 3/1.

Enfin,nous demandons au RPCpour Bloc 296452 et l'opération à l'emplacement 3/1 .

Vous verrez que lepremier code d'erreurest proto.003-psdddfki3.contract.cannot_pay_storage_fee

Failed transactions should be detected and get an error code returned in the preapply (RPC). So that this transaction even have been injected indicate a bug or bad error handling in a wallet. It is very easy to see why this transaction failed. It tried to send the full balance and wont have enough funds to cover the burn.

You can use the rpc to get the metadata. In this example you would check the ophashes on level 296452. The ophash we are interested in from your original link is onuEbjVrbaXtn4iK8KFzc4a8xTkfkyAfxiNE698SLm3MtnimdUs

The entire information regarding the block can be accessed at

https://rpc.tezrpc.me/chains/main/blocks/296452

To make it easier we can filter out the specific operation we are interested in. Operations are indexed by 2 values. The first index will always be 3 for operations done from a wallet.

https://rpc.tezrpc.me/chains/main/blocks/296452/operation_hashes/3

["ooeujV9F66p54xzKL3d8UgsdriAPwqroipLZRdVXVJKpD6oAMJA","onuEbjVrbaXtn4iK8KFzc4a8xTkfkyAfxiNE698SLm3MtnimdUs"]

The second operation hash (index 1) here is the one we are interested in, so we'll find your ophash at location 3/1.

https://rpc.tezrpc.me/chains/main/blocks/296452/operation_hashes/3/1

"onuEbjVrbaXtn4iK8KFzc4a8xTkfkyAfxiNE698SLm3MtnimdUs"

Finally we ask the rpc for block 296452 and the operation at location 3/1.

You will see that the first error code is proto.003-PsddFKi3.contract.cannot_pay_storage_fee
