FileSerializer not working in native serverless application

[prashantcodecraft]

Expected Behavior

If I am using java.io.File inside a pojo, it should be able to process in native serverless application.

Actual Behaviour

Following error is thrown :

Error encoding object [FilesUploadRequest(token=null, file=/tmp/3c5affd8-3326-4f58-be6c-3bee1c02d356748617313657626074.pdf, content=null, filetype=null, filename=3c5affd8-3326-4f58-be6c-3bee1c02d356, title=3c5affd8-3326-4f58-be6c-3bee1c02d356, initialComment=null, channels=[C05G801H5MG])] to JSON: Class com.fasterxml.jackson.databind.ser.std.FileSerializer has no default (no arg) constructor (through reference chain: com.marvin.service.connections.slack.model.slack.FilesUploadRequest["file"])

Steps To Reproduce

1. Create a native serverless application.

2. Create a Pojo with File as a type in it. for example

@Introspected(classes = File.class)
@Data
@ReflectiveAccess
@Builder
@Serdeable
@AllArgsConstructor
@NoArgsConstructor
@JsonInclude(JsonInclude.Include.NON_NULL)
public class FilesUploadRequest {
    private String token;
    private File file;
    private String content;
    private String filetype;
    private String filename;
    private String title;
}

3. Use the pojo class in application on runtime, it fails with exception

Error encoding object [FilesUploadRequest(token=null, file=/tmp/3c5affd8-3326-4f58-be6c-3bee1c02d356748617313657626074.pdf, content=null, filetype=null, filename=3c5affd8-3326-4f58-be6c-3bee1c02d356, title=3c5affd8-3326-4f58-be6c-3bee1c02d356, initialComment=null, channels=[C05G801H5MG])] to JSON: Class com.fasterxml.jackson.databind.ser.std.FileSerializer has no default (no arg) constructor (through reference chain: com.marvin.service.connections.slack.model.slack.FilesUploadRequest["file"])
