inspector2 API list_findings: cannot filter by updatedAt

Hello,

I am using the list-findings API of AWS Inspector v2, and trying to filter findings after a given updatedAt. However, no findings are returned.

More details including HTTP requests and responses are in the corresponding Github ticket for boto3 that I used to query the API. In a nutshell:

• Without the updatedAt searchCriteria, at least one finding with a value of updatedAt in March 2022 is returned;
• Performing the same query but with a updatedAt searchCriteria added asking for findings with a startInclusive in January 2022, no findings are returned.

Best regards,
