In working with Flipt V2 I found that I can create a flag resource, but if I specfy a non-existent segment, the flag is created, but leads to odd errors.
$ curl -X POST -k http://localhost:8080/api/v2/environments/default/namespaces/default/resources -d '{
"key": "flag1",
"revision": "1.0",
"payload": {
"@type": "flipt.core.Flag",
"type": "BOOLEAN_FLAG_TYPE",
"name": "flag1",
"enabled": true,
"description": "feature flag 1",
"rollouts": [
{
"type": "SEGMENT_ROLLOUT_TYPE",
"description": "enabled for fizzbuzz",
"segment": {
"key": "fizz",
"value": true,
"segmentOperator": "OR_SEGMENT_OPERATOR",
"segments": ["buzz"]
}
}
]
}
}'
I can fetch the flag using the API and see it in the UI.
But the snapshot doesn't get created right which of course means evaluation breaks:

Errors are logged:

And the UI gets unhappy as well.
