Getting ConverterNotFoundException in basic springbatch program - spring-batch

Question

I am trying to create a springboot batch application and am getting below exception
org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.util.LinkedHashMap<?, ?>] to type [#org.springframework.lang.Nullable java.util.Map<java.lang.Class<?>, java.lang.Class<java.beans.PropertyEditor>>] for value '{org.springframework.batch.item.file.transform.Range[]=org.springframework.batch.item.file.transform.RangeArrayPropertyEditor}'; nested exception is org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [#org.springframework.lang.Nullable java.lang.Class<?>]
caused by
org.springframework.core.convert.ConverterNotFoundException: No converter found capable of converting from type [java.lang.String] to type [#org.springframework.lang.Nullable java.lang.Class<?>]
It seems this error comes when spring tries to initialize org.springframework.beans.factory.config.CustomEditorConfigurer
I have not provide this bean definition in my code.
here are the key pieces of the code:
A. Job definition (in XML):
<batch:job id="testBatchJob" job-repository="jobRepository">
<batch:step id="step_test">
<batch:tasklet ref="createModifyTargetTable"/>
</batch:step>
</batch:job>
B. other definitions (in java)
#Configuration
#ImportResource({"classpath:database-config.xml","classpath:batchflows-config.xml"})
public class SpringConfig {
#Bean
public PlatformTransactionManager transactionManager() {
return new ResourcelessTransactionManager();
}
#Bean
public JobLauncher jobLauncher(JobRepository jobRepository) throws Exception {
SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
jobLauncher.setJobRepository(jobRepository);
jobLauncher.afterPropertiesSet();
return jobLauncher;
}
#Bean
public JobRepository jobRepository(#Qualifier("metadata-db") DataSource dataSource,
PlatformTransactionManager transactionManager) throws Exception {
JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
factory.setDataSource(dataSource);
factory.setDatabaseType("POSTGRES");
factory.setTransactionManager(transactionManager);
factory.afterPropertiesSet();
return factory.getObject();
}
#Bean
public Tasklet createModifyTargetTable(){
return new CreateModifyTargetTable();
}
}
