Cron error message. table or view not found: 1146
I Had this issue sometimes ago, I deleted a field table from DB manually and this error started to showing up, A way to get rid of it is to create a table for a field, so you can use a mysql code like that : 

CREATE TABLE `field_deleted_data_38d3088921` (
    `bundle` varchar(128) CHARACTER SET ascii NOT NULL DEFAULT '' COMMENT 'test',
    `deleted` tinyint(4) NOT NULL DEFAULT '0' COMMENT 'A boolean indicating whether this data item has been deleted',
    `entity_id` int(10) unsigned NOT NULL COMMENT 'The entity id this data is attached to',
    `revision_id` int(10) unsigned NOT NULL COMMENT 'The entity revision id this data is attached to',
    `langcode` varchar(32) CHARACTER SET ascii NOT NULL DEFAULT '' COMMENT 'The language code for this data item.',
    `delta` int(10) unsigned NOT NULL COMMENT 'The sequence number for this data item, used for multi-value fields',
    `test` varchar(2048) DEFAULT NULL COMMENT 'test',
    PRIMARY KEY(`entity_id`,`deleted`,`delta`,`langcode`),
    KEY `bundle` (`bundle`),
    KEY `revision_id` (`revision_id`)
)
