Parsing schema that has an object as a property value

[Ihor Levin]

I'm usinn erlavro to decode messages from Kafka, that contains the following element structure:

{
"name":Limit",
"type":["null",{
"type":"bytes",
"scale":2,
"precision":64,
"connect.version":1,
"connect.parameters":{"scale":"2"},
"connect.name":"org.apache.kafka.connect.data.Decimal",
"logicalType":"decimal"
}],
"default":null
}.

Decode function fails trying to find an unexisting clause of avro_util:ensure_binary/1, that doesn't handle the object cast ({"scale":"2"}).
Could you please help with the issue?
