CloudEventHttpMessageConverter can't convert List<CloudEvent>

[capmorganbih]

I’m trying to add an endpoint to my Spring app for batch ingestion of CloudEvents, but CloudEventHttpMessageConverter isn’t playing nice. It won’t convert to List.

What I Did
Built a Spring Boot app.
Added a REST endpoint to accept a batch of CloudEvents.
Set up CloudEventHttpMessageConverter for the conversion.
Sent a batch of CloudEvents to the endpoint.

What I Expected
I expected the converter to turn the HTTP request into a List.

What’s Actually Happening
It’s not working. The converter is failing and throwing an error instead of doing the conversion.

@RestController
public class CloudEventController {

    @PostMapping("/ingest")
    public ResponseEntity<String> ingestBatch(@RequestBody List<CloudEvent> events) {
        // Processing logic
        return ResponseEntity.ok("Batch ingested successfully");
    }
}

I've encountered the same issue. Have you resolved it?

@beyond007jj it's not supported by the SDK. The best you can do is implement your own spring converter for json + batch
