I have a lambda that does writing to an Amazon ElastiCache (Memcached) cluster every 3 minutes. But some executions are taking an exception
Connection readyState is set to readOnly
The lambda is using Runtime Node.js 12.x. The Amazon ElastiCache cluster is with Memcached engine and engine version 1.6.6 and Node Type cache.t2.micro with only 1 node. I did a test using multiple nodes and we have the same problem.
The endpoint used by the lambda is the cluster configuration endpoint and not the node endpoint.
Any suggestions to solve ? Thanks
