Indexing Error on Ingest (Keyword Search, Solr)

Running Autopsy 4.19.3 and received the following error mid Keyword Search Ingest:

Unable to add data to text index. All future text indexing for the current case will be skipped.

I presume this is occurring as Autopsy failed to index a file(s) over X times. I am not sure what the indexing is failing on and it was not evident (to me) in the log.

Is there a way / is it possible to resume indexing without having to start over from the beginning?
