How to delete the data from salesforce object? - salesforce

Question

I have a scenario where I need to delete complete data from a Salesforce object.
TO achieve, first, all the Ids from that object are fetched and saved in a file in .csv format. Once the data is uploaded into the file, need to delete the record by records in using batch.
I'm able to query on the object and save the data in .csv but while deleting the data sometimes getting below error.
Message : null (java.nio.BufferUnderflowException).
Element : /batch-delete-genericFlow/processors/3 # apl-sfa-batch-interface-v44:batch-delete-all.xml:48 (Transform Message)

Seems like Error is causing with some Value.
Please post more code to have some context.
In mean time following is a proper way of deleting SFOs.
<sfdc:delete config-ref="mySalesforceConfig">
<sfdc:ids>
<sfdc:id>001...</sfdc:id>
</sfdc:ids>
</sfdc:delete>
