Hello! I’m trying to instrument a node app, using the guide from the website I get:

> [email protected] start
> TS_NODE_BASEURL=./build node -r tsconfig-paths/register build/src/tracing.js build/src/main.js

/Users/rlopez/repos/gitstart/gateway/build/src/tracing.js:35
  .then(() => console.log("Tracing initialized"))
  ^

TypeError: Cannot read properties of undefined (reading 'then')

Seems that sdk.start() is undefined

I think start() type changed, is not a promise anymore 🤔
