Troubleshooting

Query doesn’t update properly

If you notice the result of a useQuery hook is not updating properly, you might be missing some dependencies in the query’s hash.

For example, the following query:

// Don't do this
const query$ = useQuery(queryDb(tables.issues.query.where({ id: issueId }).first()))
//                                                              ^^^^^^^ missing in deps

// Do this instead
const query$ = useQuery(queryDb(tables.issues.query.where({ id: issueId }).first(), { deps: [issueId] }))

`node_modules` related issues

`Cannot execute an Effect versioned ...`

If you’re seeing an error like RuntimeException: Cannot execute an Effect versioned 3.10.13 with a Runtime of version 3.10.12, you likely have multiple versions of effect installed in your project.

As a first step you can try deleting node_modules and running pnpm install again.

If the issue persists, you can try to add "resolutions": { "effect": "3.12.1" } or pnpm.overrides to your package.json to force the correct version of effect to be used.

Package management

Please make sure you only have a single version of any given package in your project (incl. LiveStore and other packages like react, etc). Having multiple versions of the same package can lead to all kinds of issues and should be avoided. This is particularly important when using LiveStore in a monorepo.
Setting resolutions in your root package.json or tools like PNPM catalogs or Syncpack can help you manage this.
