Function decodeValidationIssues

decodeValidationIssues(
error: unknown,
options: { source: ValidationIssueSource },
): readonly ValidationErrorItem[] | undefined
Decode Framework validation Problem Details into plain, serializable issues. The selected request prefix is removed; other sources and root errors use the empty pointer (a form-level issue). No field names are inferred.

Returns undefined for non-validation errors or malformed payloads. Keep an application-owned safe fallback for those errors. errors is Framework's Problem Details extension, not a universal RFC 9457 field-error format.
Parameters
- error: unknown
- options: { source: ValidationIssueSource }
Returns readonly ValidationErrorItem[] | undefined
Example
```
const issues = decodeValidationIssues(error, { source: 'body' });
if (issues) return { ok: false, error: 'Check your input.', issues };
throw error;
```
