Both the Ubuntu and macOS nightlies failed with an S3 authentication error only when built against the tiledb 2.26 release branch but not the dev branch. I got the exact same failures on the nightly run on my fork.

=========================== short test summary info ============================
FAILED tests/test_tiledbvcf.py::test_large_export_correctness - RuntimeError: TileDB-VCF exception: TileDB-VCF exception: Cannot open TileDB-VCF dataset; dataset 's3://tiledb-inc-demo-data/tiledbvcf-arrays/v4/vcf-samples-20' or its metadata does not exist.

I'm guessing this is related to TileDB-Inc/TileDB#5315 and TileDB-Inc/TileDB#5318. I restarted the failed jobs.

Restarted jobs failed with the same S3 authentication error. @teo-tsirpanis could you please investigate? Is this test failure related to your recent PRs?

[teo-tsirpanis]

We must set the vfs.s3.no_sign_request config option in that test.

The test did not fail on the dev Core build, because a previous PR made this option optional (in dev, if obtaining credentials fails, the request is simply made unauthenticated, which succeeds because the bucket allows public access).

TileDB-Inc/TileDB#5324 is expected to fix this.

Latest nightlies succeed after merging the above PR.
