Plugin DB error

Hi,

I get the following error in my debug log, can you help if something is missing and needs to be done to resolve this please?

WordPress database error Specified key was too long; max key length is 1000 bytes for query CREATE TABLE wp_wrc_relations (
					cache_id BIGINT(20) NOT NULL,
					object_id VARCHAR(191) NOT NULL,
					object_type VARCHAR(191) NOT NULL,
					PRIMARY KEY (cache_id, object_id, object_type),
					KEY cache_id (cache_id),
					KEY object (object_id(100), object_type(100))
				) made by require_once('wp-load.php'), require_once('wp-config.php'), require_once('wp-settings.php'), do_action('init'), WP_Hook->do_action, WP_Hook->apply_filters, WP_Rest_Cache_Plugin\Includes\Caching\Caching->update_database_structure, dbDelta

Thank you
