Fixed bug due to encodeDelimited function.

I think you might be mixing grpc-status defined here, and HTTP status codes. Can you ensure that you are using the right number range for the header grpc-status?

I got them mixed up in my initial commit but fixed them later. I am now decoding the grpc-status in method getGrpcErrorMessage .

greenlight/examples/javascript/grpc-web-proxy-client.js

Lines 34 to 55 in 11fac85

	function getGrpcErrorMessage(grpcStatusCode) {
	const grpcStatusMessages = {
	0: 'OK: The operation completed successfully.',
	1: 'CANCELLED: The operation was cancelled (typically by the caller).',
	2: 'UNKNOWN: Unknown error. Usually means an internal error occurred.',
	3: 'INVALID_ARGUMENT: The client specified an invalid argument.',
	4: 'DEADLINE_EXCEEDED: The operation took too long and exceeded the time limit.',
	5: 'NOT_FOUND: A specified resource was not found.',
	6: 'ALREADY_EXISTS: The resource already exists.',
	7: 'PERMISSION_DENIED: The caller does not have permission to execute the operation.',
	8: 'RESOURCE_EXHAUSTED: A resource (such as quota) was exhausted.',
	9: 'FAILED_PRECONDITION: The operation was rejected due to a failed precondition.',
	10: 'ABORTED: The operation was aborted, typically due to a concurrency issue.',
	11: 'OUT_OF_RANGE: The operation attempted to access an out-of-range value.',
	12: 'UNIMPLEMENTED: The operation is not implemented or supported by the server.',
	13: 'INTERNAL: Internal server error.',
	14: 'UNAVAILABLE: The service is unavailable (e.g., network issues, server down).',
	15: 'DATA_LOSS: Unrecoverable data loss or corruption.',
	16: 'UNAUTHENTICATED: The request is missing or has invalid authentication credentials.'
	}
	return grpcStatusMessages[grpcStatusCode] || "UNKNOWN_STATUS_CODE: The status code returned by gRPC server is not in the list.";
	}
