As my priority is for now not the indexer, i don't have time to find the proper way to fix the mimetype indexer (more information in the parent task).
So taking a shortcut to unstuck the indexers to avoid having them stuck in a rescheduling loop hell.
The idea is to trap the error raised.
Log in error the hash and continue indexing the rest.
A pattern like `Detecting mimetype error for id e3153c1bddd7e2e172640adc7e68dd81c6bc3167` will help.
This way, we can compulse a list of sha1 to re-index later on when the fix is found and deployed.
