I can't figure out what 'undefined' means

Environment

• Operation system: macOS/Linux
• Node.js version: 16
• Tracer version: 3.10

import tracer from 'dd-trace';

tracer.init({
  logInjection: true,
  service: process.env.DD_SERVICE,
  version: process.env.DD_VERSION,
});

export default tracer;

Every datadog log has undefind text after 'Info'.
How can I pass right value to this? I can't figure out which options is related to.

Are you using a logging package? The output kind of appears to be console.log() output, which by default has yellow numbers and green strings, which makes me think it's for local debugging instead of outputting well-formed, parseable data?

Looks like this is stale so you might have found the solution by now. I'll close it but feel free to reopen if it's still applicable!
