Ethereum: Unknown Selector Error (0x98296c54) in BIGTTokenTest.t.sol

In the lattion of the poplar smart contract framework, testbobBalance, an unexpected error. The speaking issue involves an “Unknown Selector” error, triggered wen ranning a test BIGTTokenTokenTokenTokenTokenTokenTokenTokenTokenTest.

The Issue: Unknown Selector Error (0x98296c54)*

This unknown selector occurs wen attampting to accesses The error message, "Unknown Selector 0x96c54 for VmCalls", indicades that an an-wth the contractor.

The Source Code: BIGTTokenTest.t.sol

Upon examining the code, it appeares thattestbobBalanceSpecifically, the test attampts to call theVmCallsfunction that argment, that is defined in the current.

The Problematic Line of Code

Function testbobBalance() public {

    // ... (other code)

    VmCalls(vb, 0x0000000000000000000000000000000000000000000);

}

In this line of code, VmCallsis called With an argument of argument of0x00000000000000000000000000000000000000000000000000000000000000000 Howver, the contraction’s VmCalls function exports a specific argument, it is likely to be bea value that in, that current. In this case, it appeares that no defined argument provided to the VmCalls function.

The Solution

To resolve this, it seems the author of the test is overlooked an important dele: the contract’s ed during function calls. To fix this error, the correct argument should be provided, it is likely to be a value stored in the current scope.

Here is an an updated version of the code snippt With the correected line:

Function testbobBalance() public {

    // ... (other code)

    VmCalls(vb, 0x000000000000000000000000000000000000000000000000000000 0000000000000);

}

By adding the second argument e VmCalls function, resolving the unknown error.

Conclusion*

The “Unknown Selector Error (0x98296c54) for VmCalls” is testbobBalancetest has been resolated by a logic a contract’s code. By understanding the progress and implementing the necessary fix, developers cantractly and consistently.
