Hello,
Warm greetings from AWS!

This error generally occurs if the required permissions are not granted to the user setting the DQ rules or there is some issue with DQ rules arguments.

I would suggested you to try the following Glue AWS CLI command to create the DQ rule:

For e.g.
aws glue create-data-quality-ruleset --name yellow-stone-dq --ruleset 'Rules= [IsComplete "event_key"]' --target-table '{"TableName":"noun-facts-json-table", "DatabaseName":"prod-yellow-stone"}'

Ref.
[+]  https://docs.aws.amazon.com/cli/latest/reference/glue/create-data-quality-ruleset.html

To know about the DQ DL syntax and Rule structure, please refer to this doc [+] https://docs.aws.amazon.com/glue/latest/dg/dqdl.html

In addition to above rules, IAM permissions required to add the rules are described in this doc [+] https://docs.aws.amazon.com/glue/latest/dg/data-quality-authorization.html

other documentations that you can find helpful are as follows:
