Subject: [PATCH] fix: `invalid_input` API errors may not return details (#507)

The create uploaded certificate endpoint may return the following error:

```
{
  "error": {
    "code": "invalid_input",
    "message": "certificate must use larger key size"
  }
}
```

This change ensure that we do not get a json unmarshal error (unexpected
end of json) while trying to parse a non-existing details data.

(cherry picked from commit ca78af2af8acd375460c0f9705ea9d62d5ee1cc4)
