This may be one of required fixes:

│ Warning: Argument is deprecated
│ 
│   with module.avm_res_cosmos_db_account.azurerm_cosmosdb_sql_container.this["...],
│   on .terraform/modules/avm_res_cosmos_db_account/main.sql.tf line 34, in resource "azurerm_cosmosdb_sql_container" "this":
│   34:   partition_key_path     = each.value.container_params.partition_key_path
│ 
│ `partition_key_path` will be removed in favour of the property
│ `partition_key_paths` in version 4.0 of the AzureRM Provider.
