After researching, I found that CsvSchema should be written like this, specifying the model we are converting and also defining the line and column separators:

private <T> List<T> parseData(String csvData, Class<?> modelClass) {
        try {
            CsvMapper csvMapper = CsvMapper.builder()
                    .enable(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES)
                    .disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES)
                    .build();

            CsvSchema schema = csvMapper.schemaFor(modelClass).withHeader().withLineSeparator("\n").withColumnSeparator(',');
            return (List<T>) csvMapper
                .readerFor(modelClass)
                .with(schema)
                .readValues(csvData)
                .readAll();
        } catch (IOException e) {
            throw new RuntimeException("Failed to parse CSV data", e);
        }
    }
