@lounsbrough Hi, thanks for opening the issue.
I tried to reproduce the issue, but I couldn't, I don't get the error you get.
Created a simple example running JS app on a node:22-alpine image as you shared, and I don't get any issue installing or connecting.
I'm running some commands and don't get any issue with interacting with the cluster.
Can you please share more details, that might help me locate the issue?
If you are interested, I can hope on a call when you are free for it, and I can check it with you and maybe give a live support.

@avifenesh, Thanks for the quick reply. I will try to make a minimal repro example that I can share here.

@avifenesh - sorry I just finally got back to this issue. I threw a reproduction up here: https://github.com/lounsbrough/valkey-issue-repro/blob/issue-2812/README.md

It only happens for me on Node 22, Node 20 works fine. Note also that I created this outside of Docker, so that does not appear to be the issue in my case.

Let me know if you can also reproduce the issue. Thanks for your help.

I also found that after I install a couple times (with pnpm i) then the issue goes away. For some reason the first pnpm i doesn't always install the protobuf dependencies. Maybe this is a pnpm issue? I can try to look into it a little more tomorrow.

After first install:

After second install:

@lounsbrough yes pnpm can explain it, since our CI run on node alpine latest as well, and teat the packages that been released, and i did very simple app without any workarounds so it was supposed to be reproduce.
Pnpm use different dependency mechanism by default (isolated) while npm use hoisted, so it might be that in our structure we use it from a mutual directory, but using pnpm its separated from the other dependency and its being fix by the reinstall with lock file.
Its just a guess. I will reproduce with pnpm later today.

@avifenesh please consider adding more details to installation instructions and/or update troubleshooting section

[avifenesh]

I will do it when finishing the research and have a clear understanding, currently those are just assumptions.

@lounsbrough Sorry about the delay, had some other duties this week.
Are you also copying in the lock file?

[lounsbrough]

No worries. Yes we copy the pnpm-lock.yml file during the build, and the lock file also did not change locally between installs when I was experiencing the issue. I can mess with it some more tomorrow and see if I find anything else out.
