Hey guys,  I have added clickhouse as a source, and S3 as a destination and tried to make a connection, I am getting `Failed to fetch schema. Please try again`. Does anyone know why?

Hello <@U02T5BBT9PC> could you try adding the connection using the Source Page?

Thanks <@U01MMSDJGC9> for quick reply. Trying from the source page. It is still fetching. It's been already 30 mins.

Getting same error from source page as well.

Please let  me how to fix this error. Thank you very much.

<@U02T5BBT9PC> please download the server logs and share it, probably there is the root cause error

This is not an error only a warning. From server logs there is not error; Maybe is something in the front-end side

Could you get the response in the Network tab from the call to discovery_schema endpoint?

sure, I am trying to reproduce the issue again . Takes 30-45mins.

<@U01MMSDJGC9> Captured logs from the network tab

<@U01MMSDJGC9> Just wanted to check if  anyone get a chance to look at the logs?  Thank you!

I took a look but didnt find any meaningful error there

The server logs don’t have any error (beside the warn from github)

Hi <@U02T5BBT9PC>, I have the same error here, were you able to fix it ?
Did you have to set some parameters in Clickhouse?
