baobab node: klaytn1.8.2  
client: caver-js 1.3.1

```auto
caver.klay.getTransaction('0xa866a7a53dc03b5ca9cad883a9bad0b505c5092161e8bf412d23383280367b30');

```

에서

Error: [number-to-bn] while converting number undefined to BN.js instance, error: invalid number value. Value must be an integer, hex string, BN or BigNumber instance. Note, decimals are not supported. Given value: undefined

ERROR가 발생합니다.  
caver-js 1.8.0 로 올려서 해도 동일합니다.

안녕하세요

caver-js에서 해당 트랜잭션을 파싱하는중 이슈가 있는것같습니다.

다른 트랜잭션은 정상적으로 가져올 수 있는것을 확인했습니다.

일단은 고쳐지기 전까지 아래와 같은 방법으로 Endpoint Node로 직접 요청을 보내실 수 있습니다.

## Request

```auto
const body = {"jsonrpc":"2.0","id":1,"method":"klay_getTransactionByHash","params":["0xa866a7a53dc03b5ca9cad883a9bad0b505c5092161e8bf412d23383280367b30"]};

fetch("https://public-node-api.klaytnapi.com/v1/baobab", {
  method: 'POST',
  body: JSON.stringify(body),
});

```

네 저도 caver-js 의 fomatters.js에서  
Ethereum Dynamic Fee Type 인경우  
gasPrice 없는데 포멧 변환을 하다 발생한 오류 라는 것은 알고 있습니다.  
언제 patch가 될까요?
