Known issues

edit
  • The create trained model API enforces overly restrictive input limits that may reject valid requests. A change in 8.19.17 introduced caps on description, tags, prefix_strings.ingest_prefix, prefix_strings.search_prefix, input.field_names, default_field_map, and metadata. These limits are too low for some existing use cases, including the Problemchild and DGA Security integrations, which require more than the 100-field cap on input.field_names.
