CSV generator does not support Object values for properties (nested Objects)

I have written a short test class to identify a problem I am encountering when attempting to convert a POJO to a JSON String.

NOTE that in my Java code I tried to configure the `CsvMapper` v2.18.3 to ignore certain types of problems but the `Exception` is still thrown.

Dependency:
```

com.fasterxml.jackson.dataformat
jackson-dataformat-csv
2.18.3

```

The Java code is:
```
package ca.cdr.admin.web.controller;

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.core.JsonParser;
import com.fasterxml.jackson.dataformat.csv.CsvMapper;
import com.fasterxml.jackson.dataformat.csv.CsvParser;
import com.fasterxml.jackson.dataformat.csv.CsvSchema;

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.util.Collection;
import java.util.HashSet;

public class JacksonCsvSerializationTest {

@JsonIgnoreProperties(ignoreUnknown=true)
private static class Name {
private String firstName;
private String lastName;

public Name(String firstName, String lastName) {
this.firstName = firstName;
this.lastName = lastName;
}

@JsonProperty("name")
public String getName() {
return this.firstName + " " + this.lastName;
}
}

@JsonIgnoreProperties(ignoreUnknown=true)
private static class Person {
@JsonProperty("id")
private int id = 1;

@JsonProperty("names")
private Collection names = new HashSet();

public Person(Name name) {
this.names.add(name);
}
}

public static void main(String args[]) throws IOException {
Name name = new Name("first", "last");
Person person = new Person(name);
CsvSchema.Builder csvBuilder = new CsvSchema.Builder();
CsvMapper csvMapper = (CsvMapper) new CsvMapper()
.configure(CsvParser.Feature.FAIL_ON_MISSING_COLUMNS, false)
.configure(CsvParser.Feature.FAIL_ON_MISSING_HEADER_COLUMNS, false)
.configure(JsonParser.Feature.IGNORE_UNDEFINED, true)
.configure(JsonGenerator.Feature.IGNORE_UNKNOWN, true);
csvBuilder.addColumn(new CsvSchema.Column(1, "id"));
csvBuilder.addColumn(new CsvSchema.Column(2, "names"));
CsvSchema csvSchema = csvBuilder.build().withStrictHeaders(false);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
csvMapper.writer(csvSchema).writeValue(baos, person);
System.out.println("-->" + baos.toString() + "<--");
}
}
```

The ERROR I get is:
```
Exception in thread "main" com.fasterxml.jackson.dataformat.csv.CsvWriteException: CSV generator does not support Object values for properties (nested Objects) (through reference chain: ca.cdr.admin.web.controller.JacksonCsvSerializationTest$Person["names"]->java.util.HashSet[0])

Any assistance would be appreciated!
