During migration, an error occurred.
2022-08-09 12:56:48 6 [ERROR] InnoDB: preallocating 114688 bytes for file ./financial_freedom/sessions.ibd failed with error 2
2022-08-09 12:56:48 0x7fd26c0cd700 InnoDB: Assertion failure in file /home/buildbot/buildbot/build/mariadb-10.5.16/storage/innobase/fil/fil0fil.cc line 620
InnoDB: Failing assertion: fsize != os_offset_t(-1)
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to https://jira.mariadb.org/
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to

220809 12:56:48 [ERROR] mysqld got signal 6 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.5.16-MariaDB-1:10.5.16+maria~focal
key_buffer_size=134217728
read_buffer_size=131072
max_used_connections=2
max_threads=153
thread_count=2
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467873 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...
