Error:

cleanup failed: there was an apply error: could not delete policy "test-aws-s3-19095": could not delete policy; API status code = 400; response body = {"statusCode":400,"error":"Bad Request","message":"KQLSyntaxError: Expected \")\" but \"N\" found.\ningest-package-policies.attributes.secret_references.id: (_v87RZ8Bg9k13wUkTNot or AP87RZ8Bg9k13wUkTNsu or __87RZ8Bg9k13wUkTNot)\n---------------------------------------------------------------------------^: Bad Request"}

First build failed: https://buildkite.com/elastic/integrations/builds/45770

Start with the failing policy test in cloudflare_logpush.gateway_http, specifically test-aws-s3.yml, and compare its behavior with Buildkite build 45770. Trace the cleanup failure and KQLSyntaxError involving secret_references.id; done means the test completes without the policy deletion error.
