initialize data layer failed: %w

Error message

initialize data layer failed: %w

What it means

ResetPassword wraps a failure from data.NewData(db, cache), which assembles the shared data layer (transactions, etc.) from the opened DB handle and cache. This is an internal wiring failure on top of already-initialized dependencies.

Solutions

1. Check the wrapped root error; it usually traces back to db or cache misinitialization.
2. Ensure you're on a consistent library version (no mixed modules).
3. Retry after fixing upstream DB/cache errors that left handles in bad state.

if err := cli.ResetPassword(ctx, dataDir, opts); err != nil {
    if strings.Contains(err.Error(), "initialize data layer failed") {
        log.Fatalf("data layer init failed; check DB/cache state and versions: %v", err)
    }
}

When it happens

Trigger: data.NewData errors while constructing the data layer, e.g. invalid sql.DB wrapper state, nil dependencies, or internal setup failing (rare; usually follows another init issue).

Common situations: Custom/patched data layer code failing during construction, incompatibility after version upgrade of the data package.
