Describe the problem/error/question

Hello, I attempted to use an AI Agent step that involves the SQL agent. I used the PostgreSQL credentials hosted in AWS RDS and successfully tested them. However, when I ran the step, I encountered an error.

I have enabled the ignore SLL errors

What is the error message (if any)?

hello @Antony_Rappai

I’ve had something similar. In my case, it helped to disable the option Ignore SSL Issues and set SSL to Disable state.
