During the keynote at MDBW, we had an issue during the creation of a wildcard index: https://youtu.be/SODvhxJnAcI?t=3003

Here is how I could reproduce it twice and then never again:

Compass 1.19:

• compass-data-sets, sample_airbnb. listingsAndReviews
• Create index named "wildcard", index definition [$**] - [1 (asc)]
• Click "Create index"
• shows error in the screenshots.

Then Compass master:

• delete "wildcard" on sample_airbnb. listingsAndReviews
• Create index named "wildcard", index definition [$**] - [1 (asc)]
• Click "Create index"
• shows timeout error

In both cases the index is created.

Note that this is not specific to wildcard indexes: other users had errors with regular indexes too.
