Mysql 5.7.41 & 8.0.32 backup error

[Mehmet Onur AKKAYA]

Hi everyone,
For whom is facing an error like:

The dump process failed with a none successful exitcode.
Exitcode
========
2: Misuse of shell builtins
Output
======
<no output>
Error Output
============
mysqldump: Couldn't execute 'FLUSH TABLES': Access denied; you need (at least one of) the RELOAD or FLUSH_TABLES privilege(s) for this operation (1227)

there is a bug on mysql reported below:

https://bugs.launchpad.net/ubuntu/+source/mysql-5.7/+bug/2003866

As a workaround you can remove useSingleTransaction => true from database.mysql.dump config or downgrade your mysql version.

Cheers,
Onur.
