Decoding of map[string]any behavior changed #386
Description
I noticed that the behavior of decoding a complex type of map[string]any changed between v2.19.0 and v2.20.0 and was curious if that was intended to change how avro parses this type of struct?
The test below encodes and decodes a struct that has a map[sting]any element.
If I decode with v2.19.0 I get an output of {map[a:1 b:2]} which is what I was expectingas that's the map type I encoded. But when upgrading to v2.20.0 or higher I get {map[a:map[int:1] b:map[int:2]]}
Am I doing something wrong or is this working as intended?
