Hello! I'm trying out analytics engine

Hello! I'm trying out analytics engine in my worker. But whatever I do, I always run into the Cannot read properties of undefined (reading 'writeDataPoint') error. It's a Typescript worker, and I'm simply calling env.VIEW_COUNTER.writeDataPoint() with

[[analytics_engine_datasets]]
binding = "VIEW_COUNTER"
dataset = "viewCounter"

[[analytics_engine_datasets]]
binding = "VIEW_COUNTER"
dataset = "viewCounter"

in my wrangler.toml Wrangler correctly identifies env.VIEW_COUNTER as a analytics engine dataset when generating the types;

interface Env {
    VIEW_COUNTER: AnalyticsEngineDataset;
}

interface Env {
    VIEW_COUNTER: AnalyticsEngineDataset;
}

Analytics Engine is enabled in CloudFlare. What am I missing?

Oh, I just fixed it by changing the config in wranger.toml to;

analytics_engine_datasets = [{ binding = "VIEW_COUNTER", dataset = "viewCounter" }]

analytics_engine_datasets = [{ binding = "VIEW_COUNTER", dataset = "viewCounter" }]
