I noticed today that I get

error: 500, msg: undefined

when calling the setDevicePowerState

Not the code below:

const ewelink = require('ewelink-api');
const connection = new ewelink({
    email: 'ksa*********,
    password: '********,
    region: 'us',
    });

(async () => {
    const bb = await connection.getDevice('100027d819');
    console.log(bb);
    const aa = await connection.setDevicePowerState('100027d819', 'on');
    console.log(aa);
})();

And the ouput:

Was there a change to the target API server to cause this?
