alex-kar opened a new pull request, #145:
URL: https://github.com/apache/iceberg-go/pull/145
Empty table does not have "Current Snapshot" causing describe command to be
failed.
Added validation to replace with empty string `""`.
Steps to reproduce
1. Start env `docker-compose -f dev/docker-compose.yml up -d`
2. Create namespace
```
curl --location --request POST 'localhost:8181/v1/namespaces/public/tables' \
--header 'Content-Type: application/json' \
--data-raw '{
"schema": {
"type":"struct",
"fields": [
{
"id":1,
"name": "col1",
"type": "boolean",
"required": true
}
]
},
"name": "t"
}
'
```
3. Describe table `t`: `iceberg describe public.t
--uri=http://localhost:8181`
Actual result
```
