Template the fetch chunk size.
Fix:
<!--This configuration is used to define the Service Provider name regex in DCR and IdentityApplicationManagementService-->
<ServiceProviders>
<SPNameRegex>{{service_provider.sp_name_regex}}</SPNameRegex>
+ {% if service_provider.fetch_chunk_size is defined %}
+ <FetchChunkSize>{{service_provider.fetch_chunk_size}}</FetchChunkSize>
+ {% endif %}
</ServiceProviders>
<OpenID>
