500 Server Error when using V2 endpoints to "Get NFTs" on Baobab(Klaytn testnet)

[Jun99uu]

Hello!👋
I got a 500 Server Error while fetching an NFT from Baobab chain now. It works fine on other chains, but 500 error occurs when I put "baobab" in the api's chain.
I can check out NFTs on my account on Opensea. Is this a problem I can solve?

try {
      const response: AxiosResponse<OpenSeaNft> = await axios.get(
        `https://api.opensea.io/api/v2/chain/${chain}/account/${address}/nfts`,
        {
          headers: {
            ccept: "application/json",
            "x-api-key": process.env.REACT_APP_OPENSEA_API_KEY,
          },
        }
      );
      const newNfts = response.data.nfts.map((item) => {
        return {
          //...
        };
      });
      setNfts(newNfts);
    } catch (e) {
      console.error(e);
      setNfts([]);
    }

the subdomain for testnet chains should be testnets-api.opensea.io
