Athena Query Internal Error

Question

Hello,

I have been using Athena to query json document from s3 bucket and I got below error while executing the query,

**[ErrorCode: INTERNAL_ERROR_QUERY_ENGINE] Amazon Athena experienced an internal error while executing this query. Please contact AWS support for further assistance. You will not be charged for this query. We apologize for the inconvenience.
This query ran against the "pc_slc_smtt_sustainability_db_prod" database, unless qualified by the query. Please post the error message on our forum  or contact customer support  with Query Id: 3e3e22c7-76c9-46fb-9d66-2d464a2b67a3**

I do not understand what is the issue causing this?

Answer

The issue may cause by having the reserved keywords when you run the query, here is a link to the reserved keywords and examples to run it.
https://docs.aws.amazon.com/athena/latest/ug/reserved-words.html

Also, please check your Athena engine version(https://docs.aws.amazon.com/athena/latest/ug/engine-versions-changing.html) as Athena keep releasing new engine for better performance, some syntax may not work with newer version, here is more details about the new engine improvements.(https://docs.aws.amazon.com/athena/latest/ug/engine-versions-reference.html)

Please post your query here for further investigate.

Thanks,
