Error message

Invalid culture name

What it means

Thrown by LCID.GetLCID(string culture) when the supplied culture name (e.g. 'en-US') is not found by reverse lookup in the _mappings dictionary. It performs a linear search of values and throws LiteException if none matches. Only cultures explicitly listed in the table resolve.

Solutions

1. Pass the exact culture string as listed in the LCID table (correct case and region suffix).
2. Validate/fall back: try CultureInfo.GetCultureInfo(name) and resolve its LCID via the framework instead.
3. Normalize the name (canonicalize case) before lookup.
4. Re-create the index with a supported collation name.

Example fix

// before
var id = LCID.GetLCID("en-us"); // case mismatch -> throws

// after
var id = LCID.GetLCID(CultureInfo.GetCultureInfo("en-us").Name); // 'en-US'

// canonicalize via the framework first, then look up
var name = CultureInfo.GetCultureInfo(culture).Name; // normalizes case/region
int lcid = LCID.GetLCID(name);

try { int id = LCID.GetLCID(culture); }
catch (LiteException ex) when (ex.Message.Contains("Invalid culture name")) {
    // normalize/validate the name, or fall back to invariant
}

When it happens

Trigger: Calling LCID.GetLCID with a culture name absent from the built-in table; passing a custom/neutral/mis-cased name (lookup is case-/exact-sensitive: 'en-us' won't match 'en-US'); reading a collation name not in this build.

Common situations: Mismatched casing or region suffix; locale names produced by a different runtime than the table; indexes referencing a collation whose name isn't mapped; version skew in the LCID table.
