Hey there.
I'm trying to convert the H2 DB to MySQL. The tables are created right, but the import fails with following error in console:

[11:08:44] [Server thread/ERROR]: Error occurred while enabling Craftconomy3 v3.3-e72ac42-trv178 (Is it up to date?)

Any idea what this could be?
Thanks in advance.

Same problem, this log:

same here

Oh, never posted an answer here: The problem was a huge amount of broken database-entries mostly from converting to UUIDs in the past. I was unable to show database with common h2-tool but was able to restore entries into sql-commands in a textfile. After a lot of search and replace with Notepad++ and adding 425 UUIDs manually I fixed it by myself. Since then no new inconsistencies appeared so problem solved. Sad story for other people with this kind of error.

Andorokai maybe there is a way to hack the h2 database and convert into a sql query?

i got a different errors, now last dev "work" but it trow a error and don't convert...

Table "ECO_SKYBLOCK_ACCOUNT" not found;

Corrupt database as in my case. Try fixing it with this tool: http://www.h2database.com/html/quickstart.html#h2_console
If it shows no tables you can test exporting it with build in rescue-tools. Sorry for late reply, forgot you o:-)

is not corrupt, is a prefix issue, by using cc3_ work perfect, if i select other prefix it don't work

Good to know

is not good, i can set only 1 craftconomy istance in mysql :(

Maybe if possible use a second table as a workaround.

mmm i try
use default cc3, stop the converter, then rename the table to new name and in the config, might work ^^

mmm got a different error if i use cc3_
this plugin is a mess, and data are imported from essetnials data years ago, i bet these null values are still here, @greatman please fix this
