Receiving undefined decode input from transacation

Hi, I am trying to decode input from transaction that I receive:

```
{
from: '0x1987d1c15d95cab34c154ede0a4c3bf7dba5c287',
input: '0xa9059cbb0000000000000000000000001987d1c15d95cab34c154ede0a4c3bf7dba5c287000000000000000000000000000000000000000000000000002386f26fc10000',
to: '0x8f3cf7ad23cd3cadbd9735aff958023239c6a063',
}
```

The code looks like:

```
abiDecoder.addABI(ABI);
const decodedData = abiDecoder.decodeMethod("0xa9059cbb0000000000000000000000001987d1c15d95cab34c154ede0a4c3bf7dba5c287000000000000000000000000000000000000000000000000002386f26fc10000");
console.log(decodedData);
```

But this is returning undefined.

Any thing that I am missing.

Start by inspecting the ABI supplied to abiDecoder.addABI and the decodeMethod call shown in the issue; the repository file and a failing test are not identified. Compare the transaction method selector with the registered ABI, then reproduce the call and add a focused test if the expected decoding behavior can be established.
