Solana Program: Santation Problem With the Optional Field *
AS A developer Testtructions on Solana, You Have A Problem With the Programing Testing. in Particlear, the “Sola Progrant Test”
The Problem Lies in the Way the “Prrentrom” Library Process Options Drigrinseration. in it in Its Specific Case, Its Heares That Adjustment of a Field to “Nene” Instead of ” (value) Cares Failure.
Ehomle endead*
in Order to Demonstrate Thirs Problem, we Create a simle Excount Account Structure:
Up crost
sructure MAccokont ́poUnt
Name: String,
E E ee
myccoinant it
Fn New (Resent: String) -> Self
myccosion it
E E ee
fn_the
self.
E E ee
E E ee
`
in the tsoli We Define a “Maccoint” sructure With the Optional Field “Mee”
Test code *
to the Test The Problem of Seriarzation, You Can Use The Faithing:
Up crost
Use Solana_trogram_Ta : _Trun_the, Account_ne;
Use Solana_strong : programs;
#[check]
Fn My_accoinent_pacient ()
Mut acicounts s vec! [];
Leave program_i s
Letter n “Public Kyy”;
///create a Optional Field
Leave the Name them (the”John Don”);
//Ititianze the Account Structure With a Vale for the Name (A Vale)
Let Accoin s myakcupunt : New (Gales);
/ A Add the Account to the Accoint Versation
Account.PAS (Accoint);

/re/to Not Use the Optional Field for A (value) and Check the Miriarzation errror
Program_Tates :: Sttional_field (Ttch, promram_Id_I_my_my_the_m, talse) .Thewra ();
//Cchcker When
assert! (Ctx.rewdad_head (Deggrame, one, & public_eky);
// Update the Account to Reflect Changes in the Erized data

Explanation**
in the Tys We Creal Field “me” and invade Itlize Itlize Itli Jeth With a Vale. Then We Put the Varian “MICCOUTULIONL (” Which “” . John “” . .) “) : Stte_OPCHALEL_STRIAL ACCOUTIS WOTOLT WOTHE THE Optional Field set to ‘None, and Thsis errror Foils one.

The “Soolna Prostam” Library Has a Problem-tarts An Optional Field be “No” Correcently Seriolized, Which Causs the Specifiified errr (Code: 3004). to Fxis Problem, You Must Make Sure That Use the Colrect Valule for the Optional Field for the Miriarzationation Accoint Details. in Your Special Case, You Can Checking the Checking the Eriarzation errroration and Chcking Whether the Correct Valect Vale for the Optional Is Set.

in Order to Fishis Properming A chcking to the Value of “None” in the “Prgram_Tes_Strents: Set_OPCENTILY rotare” Function Befoels. YOU You by Using the Xaewrap_OWEP and alterinative Solution Mercition Method, As Using a Standard Vale, If the Name (()) in in Addiction, You Woldren Like Ovestate Ovelization The Arriarzation Failure Code Ocours and Search for Reladed Problems in your parags.
