Hey!
while building our app we encounter a bunch of publishing task that say “Required field "xy" should appear and not be null in latest task” as well as “Required field "xy" should appear and not› be null in the sample of Zap”. All fields listed in the tasks are nested tasks. We use the output definition described here. An exerpc of the output fields is:
```
{
"key": "conversation__channel_id",
"label": "channel_id",
"required": true,
"type": "string",
},
```
both the trigger executions and the sample contain data for this field, e.g.:
```
{
"conversation”: { “channel_id”: “xyz” }
},
```
but it seems like zapier does not expect nested but flat fields. The documentation clearly states that it's possible to define nested fields using the “__” and “ ]” syntax. What am I missing here?
