An error occurred when executing the push-components task: Cannot read properties of undefined (reading 'length')

[diaiunese-at-halueio]

When I want to push a component schema by using the push-components command

Current behavior:

if a component does not contain the fields

 "internal_tags_list": [],

the push-components command will output this error:

- Executing push-components task
- Get presets from component Container
X An error occurred when load components file from api
X An error occurred when executing the push-components task: Cannot read properties of undefined (reading 'length')

And this happens because here

storyblok-cli/src/tasks/push-components.js

Line 181 in 82f4e28

if(internal_tags_list.length > 0) {

it expects internal_tags_list to be present so it checks directly its length, hence the error

Expected behavior:
If internal_tags_list is not present in the the component schema file used as <SOURCE> of the push-components command, I should be able to push the component anyway, or at least I should be informed of this missing property in a clear, informative error message so that the developer can provide it where needed.

Maybe there could be a fix on the check being executed, such as the following

if(internal_tags_list && internal_tags_list.length > 0) 

but this I'll leave it to you

Steps to reproduce:

1. create a components.json file to use as the components schema to push to Storyblok, with a component that is missing the mentioned property. For example:

{
  "components": [
    {
      "name": <COMPONENT_NAME>,
      "display_name": null,
      "created_at": <CREATION_AT>,
      "updated_at":  <UPDATED_AT>,
      "id": <ID>,
      "schema": {
        "contents": {
          "type": "bloks",
          "required": true,
          "display_name": <DISPLAY_NAME>,
          "key": <KEY>,
          "pos": 0
        }
      },
      "image": null,
      "preview_field": null,
      "is_root": false,
      "preview_tmpl": null,
      "is_nestable": true,
      "all_presets": [],
      "preset_id": null,
      "real_name": "container",
      "component_group_uuid": null,
      "color": "",
      "icon": "block-center-m",
      "internal_tags_list": []
    }
  ] 
}

3. run the push-components command, for example storyblok push-components ./components.json --space <SPACE_ID>

I seem to be getting a related error here where, if tags are populated on the source component and (presumably) the tag does not exist in the destination space the import for that component fails with a 422 Unprocessable entity

      "internal_tags_list": [
        {
          "id": <TAG_ID>,
          "name": "<TAG_NAME>"
        }
      ],
      "internal_tag_ids": [
        "<TAG_ID>"
      ],

results in

- Get presets from component <COMPONENT_NAME>
- Creating component <COMPONENT_NAME>...
X An error occurred when create component
Unprocessable Entity

If I set these arrays to be empty the import is successful.
