08 Feb Solana: First Argument Must Be Type String or Buffer” Error in SolanaAgentKit During Swap
Solana Agent Kit token SWAP error: “The first argument must enter the string or the buffer”
As a developer Solana, you are probably not a stranger to the complexity of cooperation with Solana Blockchain. One of the general issues that may arise during the application token is the first argument that was transmitted to the “Solanaagentkit.Swap” function. Specifically, the code section below illustrates this problem.
Error details
The following error message may appear when trying tokens:
`
The replacement failed: the first argument type string or the Solana program-buffer instance must be
`
This indicates that the “Swap” method is expected to be a “string” or “buffer” (modifiable view of raw binary data) as the first argument. However, instead of a valid token symbol or byte, representing the public key of the token contract, it offers a string or buffer.
Possible reasons and solutions
To solve the problem, it is possible that:
- The type of “buffer” may not be available by default.
- Make sure it is correct and appropriate to the expected format (for example, “0x1234567890abcdef”).
- Buffer difference : If the “Solana Program” package is correctly installed, check that the first argument is the buffer of the same length and type as specified in the code detail.
Troubleshooting steps
To diagnose and solve the problem:
- Check the code with any possible spelling or incorrect types.
- Check the version of the “Solana Program” package to make sure that it is compatible with the Solana 1.6.x or newer version.

Example Solution
To help solve the problem, I have set a modified example of creating a token contract and using the “Solanaagentkit” to replace:
`Javascript
Import {Createaccount} from the '@Solana/Web3.js' site;
Import {buffer} from the 'Solana program';
CONST CREATETOKENCONCONTRAKT = ASYNC (Accountid: String) => {{
Const [programid, symbol] = buffer.from ('0x1234567890abcdef', 16) .Slice (0, 4); // example token symbol
CONST ACCOUNTMETA = wait for Createaccount (
Your program,
symbol.tostring (),
{ModelDress: Accouustid},
{{
PUBKEY: Program,
}
);
Return program;
};
Conclusion
If you experience errors that are related to the first argument in the case of a “Solanaagentkit” token replacement, make sure that the token symbols and the keys are correct. Check that the “Solana program” package is correctly installed and up to date. If necessary, check the code to identify potential typing or incorrect types.
With these troubleshooting steps and examples, you should be able to solve this problem and continue to use Solana.
