IntegrationTests: Codec not found for requested operation: [TEXT <-> com.my.example.SquareToken]

I'm pretty sure this is some configuration error on my part, but I can't figure it out. From the documentation it seems like I should be able to access a repository in an integration test, but maybe not? I'm using SDC 3.4.12.

I have an integration test that is Autowiring in a repository.

public class ExampleIntegrationTest extends ControllerTestParent {
    @Autowired
    private SquareRepository squareRepository;

At the end of a test I want to do this to clean up:

squareRepository.delete(square);

This ends up throwing:

CassandraUncategorizedException: Codec not found for requested operation: [TEXT <-> com.my.example.SquareToken]

However, if I use mockMVC to call the endpoint that does a delete it works:

        MockHttpServletRequestBuilder deleteRequest = delete(squareToken).contentType(APPLICATION_JSON);
        this.mockMvc.perform(deleteRequest)
                    .andDo(print())
                    .andExpect(status().isNoContent());

I'm pretty sure that requests through the delete endpoint work because I have setup the converters, but I don't understand why the converters don't seem to be working when I use the repository in the integration test.

The @Table:

@Table
public class Square  {
    @PrimaryKey
    private SquareToken squareToken;

The converter: (I have one for SquareToken to String and String to SquareToken

public class SquareTokenToStringConverter implements Converter< SquareToken, String> {
    @Override
    public String convert(final SquareToken source) {
        return source.toString();
    }
}

And adding the converters to customConversions(). If I set a break point here I can see this method is getting called when I run the integration tests.

    @Override
    @Bean
    public @NotNull CassandraCustomConversions customConversions() {
        List<Converter<?, ?>> converters = new ArrayList<>();
        converters.add(new SquareTokenToStringConverter());
        converters.add(new StringToSquareTokenConverter());
        return new CassandraCustomConversions(converters);
    }
