I'm getting an error with TypeError: maybeGetServerSnapshot is not a function when rendering a component that calls useStoreState:

TypeError: maybeGetServerSnapshot is not a function

hey @ricardomatias - thanks for your report! We'll need to investigate this.

If you're able to create a small reproduction of this issue, it would be helpful in debugging this 👍 (we've got an example next app that you could clone)

[jmyrland]

I've bumped the versions of the example app, but I'm not able to reproduce the issue in this app.

However, I've been able to reproduce the issue in this sandbox (related to this SO post)

I'm not sure whats causing this issue, so we have to investigate this further.

I tried the example project that you referenced and it works fine. The only common information I could find on another project was this.

I think the changes in #823 might remedy this issue.

@ricardomatias could you install easy-peasy@5.2.1-alpha.0 to see if this fixes your issues?

The error is gone, thanks @jmyrland!

The error is gone, thanks @jmyrland!

Thanks for verifying 👍 I'll either publish a separate release with this change, or it will be a part of the upcoming v6-release.

Until then, you can just rely on the alpha release above.
