Can not execute the operation on ended Span {traceId: 87464894ec5751e4af73cb8915bb4830, spanId: 0410a78c7f08acb2}

Guess thats coming from the fact that i'm trying to guess if one layer called the next callback or not (here). I will look into it tomorrow if no one does it before

Yes, looks like due to:

opentelemetry-js/packages/opentelemetry-plugin-express/src/express.ts

Lines 210 to 212 in f695e40

	if (callbackHasBeenCalled === false) {
	span.end();
	}
