未捕获的异常回调不是函数{“ stack”：“ TypeError：回调不是回调函数（/home/akkastech/backend-api/node_modules/nexmo/src/index.js:171:23)\\n HttpClient.callback [as __parseResponse]（/home/akkastech/backend-api/node_modules/nexmo/src/HttpClient.js:181:7)\\n在IncomingMessage .__ parseResponse（/ home / akkastech / backend-api / node_modules / nexmo /src/HttpClient.js:93:16)\\n在emitNone（events.js：111：20）\\ n在IncomingMessage.emit（events.js：208：7）\\ n在endReadableNT（_stream_read.js：1055： 12）\\ n在_combinedTickCallback（内部/进程/next_tick.js:138:11)\\n在process._tickCallback（内部/process/next_tick.js:180:9）“}

Answer 1

it looks like you're passing something as a callback parameter that's not actually a function. It should look like this:

nexmo.message.sendSms(from, to, text, (err, responseData) => {
    if (err) {
        console.log(err);
    } else {
        if(responseData.messages[0]['status'] === "0") {
            console.log("Message sent successfully.");
        } else {
            console.log(`Message failed with error: ${responseData.messages[0]['error-text']}`);
        }
    }
})
