Adding FilePart to the Job Parameter is not working

[premcody]

I've tried to add FilePart Object to the JobParameterBuilder but getting the error "No Suitable Convertor to perform conversion from DefaultFilePart to String".

org.springframework.core.convert.converternotfoundexception: no converter found capable of converting from type [org.springframework.http.codec.multipart.defaultparts$defaultfilepart] to type [java.lang.string] + spring batch 6.0.2

Here is the code snippet :

 FilePart filePart = (FilePart) partMap.get("importFile");
   JobParameters jobParameters = new JobParametersBuilder()
                          
                            .addString("batchId", batchId.toString())
                           
                            .addString("some1", some)
                            .addString("app", appCodePart.value())
                            .addString("dskey", datasourceKeyPart.value())
                            .addString("table", tableNamePart.value())
                            .addString("emailAddress", emailAddressPart.value())
                            .addString("fileName", filePart.filename())
                            .addString("mode",uploadMode)
                            .addJobParameter("filePart",filePart,FilePart.class)
                             
                            .toJobParameters();

Spring batch version: spring-batch-core-5.0.2
Spring boot: 3
spring-core-6.0.11

This was working atleast before (Spring-batch-core 4x versions) as i'd added FilePart as jobparameter using addparamter method but now failing with spring-batch-core 5.0.2 and spring-core-6.0.11.

I think the problem is here the filepart is really not assignable to/from String as per the Spring-core code(JdbcJobExecutionDao,GenericConversionService & TypeDescriptor).

Adding the Stacktrace.
