LaravelCacheStore throws error for database (MySQL) and failover cache drivers

[oddvalue]

When using the database or failover laravel cache drivers the rate limiter store throws a "The store was unable to update the limit." error.

This has been tested and confirmed with a MySQL database. The issue is not present for SQLite databases.

The issue appears to be caused by the too_many_attempts_limit value not changing between requests and the cache store returning false because although the caching was successful, nothing was updated.

Yep, that was exactly the issue, no data was updated and the plugin currently treats that as not successful. I've just pushed #23 which adds a check into LaravelCacheStore to see if the data already exists and just return true if it does.
