When does this happen?
IF A Zod schema for a GitLab project API response includes a required `fork` field, but the GitLab API only returns that field for forked projects, causing validation errors.
How others solved it
THEN Make the `fork` field optional in the schema (e.g., `fork: z.boolean().optional()`) to handle both forked and non-forked projects. Alternatively, remove the field if not required. Always check API documentation for conditional fields and design schemas accordingly.
// Before (causes errors):
const GitLabRepositorySchema = z.object({
...
fork: z.boolean(),
});
// After (handles missing fork):
const GitLabRepositorySchema = z.object({
...
fork: z.boolean().optional(),
});Related patterns
