Okay. This script can reproduce the bug.

set -x
curl localhost:8080/query -XPOST -d 'mutation {
set {
     _uid_:0xc1cee22c7ab32e68 <type.object.name.en> "Cars" .
		   
}

}'

curl localhost:8080/query -XPOST -d '{
me(_uid_: 0xc1cee22c7ab32e68 ) {
      type.object.name.en
}
}
}'

echo "Sleeping for 15s"
sleep 15

curl localhost:8080/query -XPOST -d '{
  me(_uid_: 0xc1cee22c7ab32e68 ) {
      type.object.name.en
    }
  }'

curl localhost:8080/query -XPOST -d 'mutation {
  delete {
     _uid_:0xc1cee22c7ab32e68 <type.object.name.en> "Cars" .
  }
}'

curl localhost:8080/query -XPOST -d '{
  me(_uid_: 0xc1cee22c7ab32e68 ) {
      type.object.name.en
    }
}'

curl localhost:8080/query -XPOST -d 'mutation {
  set {
     _uid_:0xc1cee22c7ab32e68 <type.object.name.en> "newcar3" .
  }
}'

curl localhost:8080/query -XPOST -d '{
  me(_uid_: 0xc1cee22c7ab32e68 ) {
      type.object.name.en
    }
}'

curl localhost:8080/query -XPOST -d 'mutation {
  delete {
     _uid_:0xc1cee22c7ab32e68 <type.object.name.en> "newcar3" .
  }
}'

curl localhost:8080/query -XPOST -d '{

      type.object.name.en
    }
}'
