   @alamb I just tried this on 45.0 and it still doesn't seem supported:
   
   ```
    Failed to collect data frame results: Plan("Cannot cast file schema field 
additionalInfo of type Struct([Field { name: \"location\", data_type: Utf8, 
nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }, Field { 
name: \"timestamp_utc\", data_type: Timestamp(Millisecond, Some(\"UTC\")), 
nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }]) to table 
schema field of type Struct([Field { name: \"location\", data_type: Utf8, 
nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }, Field { 
name: \"timestamp_utc\", data_type: Timestamp(Millisecond, Some(\"UTC\")), 
nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }, Field { 
name: \"reason\", data_type: Struct([Field { name: \"_level\", data_type: 
Float64, nullable: true, dict_id: 0, dict_is_ordered: false, metadata: {} }, 
Field { name: \"details\", data_type: Struct([Field { name: \"rurl\", 
data_type: Utf8, nullable: true, dict_id: 0, dict_is_ordered: false, metadata: 
{} }, Field { 
 name: \"s\", data_type: Float64, nullable: true, dict_id: 0, dict_is_ordered: 
false, metadata: {} }, Field { name: \"t\", data_type: Utf8, nullable: true, 
dict_id: 0, dict_is_ordered: false, metadata: {} }]), nullable: true, dict_id: 
0, dict_is_ordered: false, metadata: {} }]), nullable: true, dict_id: 0, 
dict_is_ordered: false, metadata: {} }])
   ```
   
   Do I need to flip a flag or something?
