failures:
    aws::tests::s3_test

test result: FAILED. 145 passed; 1 failed; 4 ignored; 0 measured; 0 filtered out; finished in 15.49s

Expected behavior
Test should pass

Additional context
It appears to have first failed with this PR:

• Return BoxStream with 'static lifetime from ObjectStore::list #6619

However, the tests passed when run on that PR ( https://github.com/apache/arrow-rs/actions/runs/11842800687/job/33002269831) which suggests to me this is related to some change in the environment / emulator rather than our code

The test passed a day before on main

There is an example from this PR where where the emulator test passes on a rerun

• Use u64 range instead of usize, for better wasm32 support #6961
• Failure: https://github.com/apache/arrow-rs/actions/runs/12770295148/job/35594807418?pr=6961
• Success (same code): https://github.com/apache/arrow-rs/actions/runs/12770295148/job/35607985446?pr=6961
