Hi @yuuuuuuuji
Which version of Metabase?
Which database are you using for metadata?
Do you see other errors? The error is Caught error running {0}, which doesn’t give any hints to what the problem could be.

HI @flamber

Version:v0.33.0

Umm,i will find any hints…

@yuuuuuuuji
Latest release is 0.33.3
I have a feeling that you’re not using utf8mb4 as charset/collation for the database/tables/columns, so make sure they’re all using that - and that should fix your problem.

@flamber

I downgraded metabase because other bug
(Changing the visualization method makes the time display strange)

mysql> show variables like “chara%”
-> ;
±-------------------------±------------------------------------------+
| Variable_name | Value |
±-------------------------±------------------------------------------+
| character_set_client | utf8 |
| character_set_connection | utf8 |
| character_set_database | utf8 |
| character_set_filesystem | binary |
| character_set_results | utf8 |
| character_set_server | latin1 |
| character_set_system | utf8 |
| character_sets_dir | /rdsdbbin/mysql-5.7.22.R5/share/charsets/ |
±-------------------------±------------------------------------------+

is this?

@yuuuuuuuji
Run the commands that I have listed in https://github.com/metabase/metabase/issues/10691
And no, utf8 is not the same as utf8mb4 - specially not, when you’re using Japanese characters.

OK,Thank you.
