Which version of Druid are you on?

29.0.1

This error mostly pops up if you don’t have “druid-multi-stage-query” loaded

ok let me check and if not let me add that extension and revert thanks

Were you able to ingest the data (as in the second screenshot)

yes i am able to ingest the data ..however i get this error also.. not sure what is giving 404 here. This gives error but when i see datasources data is loaded.. can you tell me what is happening here.
