Fix display of values in Topic detail if schema has more than one type

[chrisjbremner]

I noticed that on the topic detail page, if I have a topic with the following Avro schema:

key1 -> [null, string]
key2 -> string

Then when a message is displayed in the topic detail page, it shows up as:

{
  "key1": {
    "string": "value1"
  },
  "key2": "value2"
}

Ideally, it would display as:

{
  "key1": "value1",
  "key2": "value2"
}

I inspected the messages websocket and confirmed that the message that was displayed came from the backend. I suspect what is returned is simply what Kafka stores internally, but I was wondering if it's possible to strip out these types when deserializing from an Avro schema?

@chrisjbremner I just pushed a commit that potentially fixes this. Could you give it a spin? If this hasn't fixed it I'm afraid I can't do much about it and in that case it might make sense to submit an issue in the repo of the go-avro client maintained by Linkedin.

Just tried out kowl:master-06fbeced but looks like the issue still persists. Thanks for giving it a shot, I will submit to go-avro

Oof, go-avro doesn't look like it's actively maintained anymore

Looks like someone already made one (linkedin/goavro#167) there's linkedin/goavro#201 that fixes this, but it's been open for a while and hasn't been merged
