Hello,

Could you please give us some detailed step to reproduce your issue?

In addition, if you don't mind, could you please open the error log generated automatically by the Studio to see whether you have error stack trace there; if you do, we will appreciate it a lot if you can paste it here.

About how to open this error log: in your Studio, click Window to open the menu, then select Show View->General->Error Log. Once you see an error, double click it.

Best regards

Hello,

Can Snowflake components be displayed from your palette?

I'm supposing that your installation of Talend Real-time big Data Platform is not complete as snowflake components are available in Talend Real-time big Data platform solution.
