How can I fix the query with this alert message?

Hello, I usually use redash to analyze data.

In this morning, I found that some of queries does not work with this alert message, and I cannot find where the problem occurred.

Can you help me? I attach the alert message.

Thanks.

Did you try Googling it? It’s an error from your Redshift instance. You can see a discussion of it in the AWS Docs.
