Function validateRequiredFields

validateRequiredFields(
    config: Record<string, unknown> | null | undefined,
    requiredFields: string[],
    options?: ValidatorOptions,
): { valid: boolean; error: string | null; missing: string[] }
Checks that an object carries a set of required top-level fields.

Reports every missing field at once through the extra missing array, rather than stopping at the first — a configuration error is more useful complete.
Parameters
- config: Record<string, unknown> | null | undefined
  Object to inspect; null or undefined counts every field as missing.
- requiredFields: string[]
  Names that must be present.
- options: ValidatorOptions = {}
  See ValidatorOptions.
Returns { valid: boolean; error: string | null; missing: string[] }
{ valid, error, missing }, where missing lists the absent names.
Throws
GeoLeafError A ValidationError when fields are missing and throwOnError is set.
Example
```
const config = { map: { target: "my-map" } };

const result = GeoLeaf.Validators.validateRequiredFields(config, ["map", "layers"]);
// Returns: { valid: false, error: 'Missing required fields: layers', missing: ['layers'] }

const result2 = GeoLeaf.Validators.validateRequiredFields(config, ["map"]);
// Returns: { valid: true, error: null, missing: [] }
```
