Cluster client throws "TypeError: Cannot read properties of undefined (reading 'redis')" on AWS Elasticache Serverless Valkey

[ekscentrysytet]

Hi community! Thanks for the fork and your work maintaining this lib!

We've deployed our app that connects to AWS Elasticache Serverless Valkey cluster as:

const valkey = new Valkey.Cluster(
    [
      {
        host: "...",
        port: "...",
      },
    ],
    {
      clusterRetryStrategy(times) {
        if (times > 60) {
          return null
        }

        return 1000
    },
      dnsLookup: (address, callback) => callback(null, address),
      redisOptions: {
        password: "..."
        username: "...",
        maxRetriesPerRequest: 2,
        commandTimeout: 500,
        tls: {
          rejectUnauthorized: false,
        },
      },
    },
  )

And everything worked fine, untli we started to see following errors in logs:

Cannot read properties of undefined (reading 'redis')","stack":"TypeError: Cannot read properties of undefined (reading 'redis')

By discovering repo, I can see it's related to changes made in this PR: #5.

I guess the issue also can be related to AWS Elasticache Serverless runtime.
Did anyone face such issue ?

Thanks for pointing that out! I made a quick attempt to fix the immediate issue in #32.

However, that fix might not be sufficient to address the overall issue you are facing.

I think it's closed now in: #34
But we decided to switch to https://github.com/redis/node-redis which is works stable for us for last 3 weeks
