How do I resolve the Rule Testing error "ResourceNotFoundException" in Panther?


When trying to test a rule with mocked functions the following error occurs:

[FAIL] [rule] ResourceNotFoundException: An error occurred (ResourceNotFoundException) when calling the UpdateItem operation: Requested resource not found


To resolve this issue, check your mock function names to ensure they match the ones called in your rule.

If this fails, and you're using panther_analysis_tool to test/upload your detections, ensure that the environment the rules are based in is cloned from our panther-analysis GitHub.


This issue occurs when a function called in the rule cannot be found.
