           async fn test_fetch_info(index: Index) { 
        
               let index = index.fetch_info().await;

See the following github-action: https://github.com/meilisearch/meilisearch-rust/runs/6306804797?check_suite_focus=true

Not sure when it was introduced

Expected behavior
Always succeed

Current behavior
Regularely fail.

Any idea @irevoire ?

Ok, so from what I see, the failure comes from the macro, which means neither this test nor #281 are flacky. The index creation is flaky and thus all our tests are flaky 😬

fixed by #285

	async fn test_fetch_info(index: Index) {
	let index = index.fetch_info().await;
	assert!(index.is_ok());
	}
