Your _source_ (i.e. cdcr_testa) doesn't have the CDCR update log configured.
This section isn't in solrconfig for cdcr_testa:
<updateHandler class="solr.DirectUpdateHandler2">
<updateLog class="solr.CdcrUpdateLog">
<str name="dir">${solr.ulog.dir:}</str>
<!--Any parameters from the original <updateLog> section -->
</updateLog>
</updateHandler>
The update log is the transfer mechanism between the source and target
clusters, so it needs to be configured in both.
Best,
Erick.
P.S. kudos for including enough info to diagnose (assuming I'm right)!
