The .omit() method appears to fail when chained after .extend() on a createInsertSchema() result.

export const insertLocationSchema = createInsertSchema(locations)
  .extend({
    city: z.string().min(1, { message: "City is required." }),
    state: z.string().min(1, { message: "State is required." }),
  })
  .omit({
    id: true,
    createdAt: true,
    updatedAt: true,
  });

export const insertLocationSchema = createInsertSchema(locations)
  .extend({
    city: z.string().min(1, { message: "City is required." }),
    state: z.string().min(1, { message: "State is required." }),
  })
  .omit({
    id: true,
    createdAt: true,
    updatedAt: true,
  });
