This is definitely related to the changes to the yaml tests in #96763.

Considering the get counter-part of these tests are stable: https://gradle-enterprise.elastic.co/scans/tests?search.buildOutcome=failure&search.relativeStartTime=P28D&search.timeZoneId=Europe/Berlin&tests.container=org.elasticsearch.backwards.MixedClusterClientYamlTestSuiteIT&tests.test=test%20%7Bp0%3Dget/40_routing/Routing%7D, I think I will do the same change I did for them in e.g. 5010402#diff-1a03b7062c6c3043dd19a62f75a04497c5a75e4b23da81ed927009345994252c, and see if that would work for mget too.
