There seems to be an issue with how products are migrated from Magento 1.9 to Magento 2.3. All products are imported fine, but when Elasticsearch goes to get a query, it fails on:
aused by: java.lang.IllegalArgumentException: Fielddata is disabled on text fields by default. Set fielddata=true on [links_title] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead
links_title is of course an EAV attribute for downloadable products, of which we have none. It is almost like since there are no values set for this EAV, it is defaulting to one, and Elasticsearch doesn’t like the data type.
Have you seen this issue before? Any advise? The pro tool does work great, this is one of the last issues we have to resolve now.
