Scalatest "At least one" instead for Forall

I wrote this test method in Scala to test a REST service.

@Test def whenRequestProductInfo() {
  // When Request Product Info
  forAll { (productId: Int) =>
      val result = mockMvc().perform(get(s"/products/$productId")
        .accept(MediaType.parseMediaType(APPLICATION_JSON_CHARSET_UTF_8)))
        .andExpect(status.isOk)
        .andExpect(content.contentType(APPLICATION_JSON_CHARSET_UTF_8))
        .andReturn;

      val productInfo = mapper.readValue(result.getResponse.getContentAsString, classOf[ProductInfo])

      // At least one is not null
      // assert(productInfo.getInventoryInfo != null)
  }
}

But I want to test that at least one productInfo.getInventoryInfo is not null instead of every productInfo.getInventoryInfo is not null.
