Airbyte

Hey,
I am learning to build an http source connector. I mentioned   `supported_sync_modes": ["full_refresh","incremental"]` in `configured_catalog.json` for a stream but in airbyte UI (local) when I try to set up the sync it only shows `full_refresh`  as an option for source connector, any idea how to resolve this?

Have you tried rebuilding the connector and/or redeploying your local airbyte instance?

Hi <@U03J7N2M6BD>,
Yes, I have tried it just now but it still does not show the incremental option , here is my `configured_catalog.json` file and the UI picture
```{
    "streams": [
      {
        "stream": {
          "name": "nextlab",
          "json_schema": {
            "type": "object",
            "properties": {
              "token_id": {
                "type": "string"
              }
            }
          },
          "supported_sync_modes": [
            "full_refresh",
            "incremental"
          ]
        },
        "sync_mode": "incremental",
        "destination_sync_mode": "overwrite"
      }
    ]
  }```

Just to be clear, you followed all of the instructions here under "<https://docs.airbyte.com/contributing-to-airbyte/developing-locally/#add-a-connector-under-development-to-airbyte|add a connector under development to Airbyte>" right? My guess here is that the connector you're interacting with in the UI is an old version of the connector that hasn't been updated, which is why it's not showing the incremental sync mode. I'm definitely not 100% sure so I just want to cross everything trivial off the list before we consider it a bug.

<@U03J7N2M6BD> I have followed the steps and it's the newer version but I found the problem ( I think ).
I just found that the incremental sync needs a `cursor_field` for airbyte to identify it as an incremental sync ( I am pretty new to this, I did not know this until I saw that )
