sendPeersProposal は、どうも fabcar の queryByChaincode でも使われているため
offlineの時と、onlineの時で何がちがっているか調べる。

responseが変わる意味がわかるかもしれない

とおもったら、いっしょのが返ってきたっぽい？
sendPeersProposal の段階ではデータ返ってきているが、
sendSignedTransaction の responseはちゃんと返ってきていないのは、、、なぜz？

以下場所で　
==== sendSignedProposal === Promise { }
になってしまう。これが原因。

	async sendSignedProposal(request, timeout) {
		const responses = Channel.sendSignedProposal(request, timeout);
		console.log('==== sendSignedProposal ===', responses);
		// console.log('1====sendSignedProposal==== responses.response', responses[0].response.payload.toString());
		return responses;
	}

と、色々書いたが以下のメソッドのresponseで拾えていた 😓

  const proposalResponses = await channel.sendSignedProposal(sendSignedProposalReq)
