mysqldump: Couldn't execute 'show fields from `wppe_uap_trigger_logs_view

Symptoms

You may come across the following errors during backup:
The backup process encountered the following error:
[2020-12-05 02:12:21 +0200] mysqldump: Couldn't execute 'show fields from `erhard_example_cal_events_p3`': Incorrect file format 'erhard_example_cal_events_p3' (130)or
[2022-11-29 02:29:59 -0500] mysqldump: Couldn't execute 'show fields from `prefix_table`': Can't find file: './user_db/prefix_table.MYI' (errno: 2 "No such file or directory") (1017)Description

The error means that mysqldump was not able to view the table's fields. As we can see below the table that reported the issue has a size of 0 which means that a corruption occurred and the table is empty.
# ll /var/lib/mysql/thisisanexample | grep events

Workaround

Restore the table manually from backup or restore a whole account backup of the affected user.

Additional resources:
Restore a single database from a MySQL data directory backup

Restore an account from a backup file on the server

If you do not know which database holds the table that is having issues. Use the following query:

mysql> select table_name,table_schema as dbname FROM INFORMATION_SCHEMA.TABLES WHERE table_name='mytable_mytable';

+-----------------+--------------+

| table_name | dbname |

+-----------------+--------------+

| mytable_mytable | myfavouritedatabase |

+-----------------+--------------+

1 row in set (0.06 sec)

Please note, in the above example,
mytable_mytable needs to be replaced with the correct table name.
