Unable to disable the automatic SHADOW_GET message on (re)connect

[ghost]

I need to disable the automatic SHADOW_GET message on MQTT (re)connect. As per documented note in the mgos_shadow.h header file i tried different configurations, but none of them worked fine.

The note in mgos_shadow.h header file says:

/*
 * Request shadow state. Response will arrive via GET_ACCEPTED topic.
 * Note that MGOS automatically does this on every (re)connect if
 * device.shadow.get_on_connect is true (default).
 */
bool mgos_shadow_get(void);

1. I tried adding this to conf0.json, but it didn't work.

{
  "device": {
    "shadow": {
      "get_on_connect": false
    },
    ...
  },
  ...
}

2. I tried adding this to conf0.json, but it didn't work.

{
  "shadow": {
    "get_on_connect": false,
    ...
  },
  ...
}

3. I tried adding this to conf0.json, but it didn't work.

{
  "aws": {
    "get_on_connect": false,
    "shadow": {
      "get_on_connect": false
    },
    ...
  },
  ...
}

Could you suggest me how to fix it?
I thank you in advance.
Best Regards

This is very VERY old but i just got into the same problem and posting the answer here in case others encounter the same.
If you want to completely disable shadow service put this in your mos.yml:
- ["shadow.enable", "b", false, {title: "Request shadow state on connect"}]

And here is the entire shadow section fo the config file that you can modify - FYI - when i was working on flee provisioning in AWS IoT Core where broker accepts only specific payload on specific topic i had to disable the shadow service completely ( disabling getting it on connect was not enough for some reason ) in order to get certificates back.

  "shadow": {
    "enable": false,
    "get_on_connect": true,
    "lib": ""
  },

Also - no idea why but when i tried to connect to aws iot only using pure mqtt without the AWS lib - it didn't work, you always need to have aws library imported into your project to properly communicate and parse the responses.
Hope that help.
