Incompatible issue while synchronizing cloud and local database

Question
1

Hello guys!

I’m trying to populate my local storage database with the data from REST API request by using “Replace client-side record collection” flow function from market. I use these threads as how-to, but still can not manage to make it work. Because of the incompatible issue, of course. Please, HELP :pray:

This is what I have so far:

  1. Airtable table creatures_list

  2. That I successfully fetch to my app as airtable_creatures_list data source

    get_request
    get_request702×500 14.1 KB

  3. That has the next scheme

    get_schema

  4. Also I prepared a client-side storage local_creatures_list with the same scheme

    local_storage

  5. I am trying to bind them on the global canvas

    global_canvas_flow

  6. But there appears the incompatible issue

Could you please give me any suggestion how to fix this?

And one more additional question: why do those guys from topics mentioned above use app variable? What are the advantages of referencing schemeless app_variable instead of local storage?
