TypeError [ERR_INVALID_CHAR]: Invalid character in header content ["Host"]

I'm using superagent as a rookie programer, but get stuck on below issue, please shed some light on it, many thanks!
Due to some reasons, we still using old version of Election, maybe this is not the root cause.

Electon: v4.x,
Node.js: v8.x
Superagent: v6.1.0

Code snipet:
// -----------------------------------------------
let errorCount = 0;
for (let i=0; i= 3) break;
}
}

// -----------------------------------------------
process.on('uncaughtException', function(err) {
loggerSys.error(err);
app.exit(900);
});

//--------------------- log -------------------
