addSource("{id}") was already registered; returning the existing source handle. Use a distinct id per feed.

Warnings reference › data-router:duplicate-source

Identifier

data-router:duplicate-source

Raised by

Data Router

Since

1.34.0

What happened

Two feeds were registered under one id. The second call did not create a second source: it returned the handle of the first, so both callers are now pushing into the same stream and the options of the second registration were ignored entirely.

The fix

Give each feed its own id, or keep the handle from the first addSource instead of calling it again.

The smallest fix

const trades = router.addSource('trades');
const quotes = router.addSource('quotes');
