04/05/2023, 8:52 AMDoes your kafka stream have data?

04/05/2023, 9:12 AMAre you sampling from the start of the stream? If not, it looks for data appended after you begin sampling and may not return data if no new data is being consumed

04/05/2023, 9:24 AMCould you please check the response and error using your browser's developer console? I wonder if the consumer properties related to auth are missing

04/05/2023, 9:53 AMAre you perhaps trying to edit a very old sepc (2021.07 or earlier i think) https://docs.imply.io/latest/druid/ingestion/ingestion-spec/#legacy-dataschema-spec

04/05/2023, 3:57 PMit is giving you an error about missing timestampSpec because your timestamp spec is missing, you have not gone though all the steps of the data loading wizard so it did not finish making a spec for you. You can write a spec by hand and submit it, you do not have to use the spec building wizard. But if the sampler can not fetch any data likely something is wrong. Is your Druid able to reach your kafka bootstrap server at 178.128.113.56:9092 ?

04/05/2023, 10:55 PMif you manually write an ingestion spec like this example, you can submit it via the API or via the console
