Description

Hi,
Here is the step to reproduce the problem:

• ddl

  drop dataverse test if exists;
  create dataverse test;
  use dataverse test;
  
  create type t1 as open{ 
      id: int64,
      name: string
  }
  
  create dataset ds1 (t1) primary key id;
  
  create feed fd2 using socket_adapter
  (
      ("sockets"="nc2:10001"),
      ("address-type"="nc"),
      ("type-name"="t1"),
      ("format"="adm"),
      ("duration"="1200")
  );
  set wait-for-completion-feed "false";
  connect feed fd2 to dataset ds1 using policy AdvancedFT_Discard;
  

• Create and drop an unrelated temporary dataset

  create temporary dataset tmp_tweets(t1) primary key id; 
  drop dataset tmp_tweets
  

  Then the expection appears as below

The drop statement will work fine if we didn't set up the feed adapter.
