yongkyunlee opened a new issue, #8270:
URL: https://github.com/apache/arrow-rs/issues/8270
**Describe the bug**
Decoder flush panics when the value field of a map type contains metadata
(e.g. enum type)
**To Reproduce**
When we generate avro data with a map field whose value type is enum, the
decoder panics at flush with an error like below
```
thread 'reader::record::tests::test_map_entries_with_enum_value' panicked at
arrow-array/src/array/map_array.rs:132:64:
called `Result::unwrap()` on an `Err` value: InvalidArgumentError("MapArray
expected data type Struct(key Utf8, value Dictionary(Int32, Utf8)) got
Struct(key Utf8, value Dictionary(Int32, Utf8)) for \"entries\"")
```
**Expected behavior**
Flush should be successful with any valid `value` field type of a map.
