Error “KeyexcludfromoscandyyindexMessage” when using Get_Program_accouts' For SPL in Solana
As a developer of applications in the Solana blockchain, it is essential to understand the subtleties of the Solana ecosystem. In this article, we will deepen an error that occurs when using theGET_PROogram_-sable function from the“ Solan-PY ”library to recover the 100-principal holders of a SPL specific token.
A question: KeyexcludfromosandyindexMessage
When you call “Get_Program_accouts”, Solana returns a list of program account, which are the addresses that have access to the blockchain. However, in some cases, a key may be excluded from this secondary index message for several reasons, such as:
- The account is not authorized for transaction or reading.
- The account has been disabled.
- There is a problem with the configuration of the program account.
In our case, the error “KeyexcludedffffffromoscondaryindexMessage” occurs when “Get_Program_accouts” returns a list of accounts that have no program associated with them. This is generally due to the following reasons:
- The user has limited access to the account.
- The account that has the account is not allowed to be included in the secondary index.
Why you will find an error
If you find an “error: KeyexcludedfromeCondaryIndexMexMesage” when you use Get_Program_Accouts' for your token SPL, here are some potential reasons:
- Missing programs : The program that has the account may not have associated with it.
- Restricted access
: The user has restricted access to the account or the program.
- Program configuration questions : There is a problem with how the program is configured.
How to correct the problem
To solve this problem, you can try the following steps:
- CheckGet_ProgramM_accouts’ Call : Make sure you call the necessary arguments correctly.
- Check access to the account : Make sure the user has access to the account by checking his authorizations with the documentation of the Solana API.
- Adjust the program configuration : If possible, adjust the program setting to grant access to the account or modify its rules.
Code example
Here is an example of how you can use Get_Program_accouts to recover the 100 main carriers of a SPL SPL SPLA Solana tokens:
`Python
Import Solana.publickey like PK
Solana import programs Get_ACCOUNT, Get_account_info
Def Main ():
Define your account identifier and the name of the SPL token
Account_id = "your_account_id"
SPL_TOKEN_NAME = "your_spl_token_name"
Create an instance of the client with the Solana Crica tool
from Solana.web3 Import Web3
Web3 = Web3 ()
Get account information for your token SPL support
SPL_TOKEN_HOLDERS = Get_Program_accouts (Web3, account_id, SPL_TOKEN_NAME)
Print ("Top 100 carriers", SPL_TOKEN_NAME)
Print (SPL_TOKIN_HOLDERS [: 100])
If __name__ == "__main__":
main()
'
Conclusion
In this article, we explore an error that occurs when usingGet_Program_ -Counts” to recover the 100 main supports of a specific token spl in Solana. Understand the potential reasons for this error and follow the steps described in the example, you can solve the problem and successfully use `Get_Program_accouts’ with your MEP support.
