EzShops 2.5.9: SQL transaction repository fails with "DataSourceJdbcStore does not support flat-map operations" #84

Hi,

I’m testing EzShops 2.5.9 on a Folia 26.2 server and I’m running into an issue with SQL transaction logging.

My setup is:

Folia 26.2
Java 26
EzShops 2.5.9
VaultUnlocked 2.20.2
EternalEconomy 1.0.1
MariaDB 12.3.2

MariaDB itself seems to be working fine. On startup EzShops says:

Shop transactions: using SQL-backed transaction repository.
Player shops: using Jaloquent storage (JDBC adapter).
EzShops plugin enabled.

The problem happens whenever I sell something, for example:

/shop sell IRON_INGOT 10

The sale itself seems to work, but every time I do it I get this error in console:

DataSourceJdbcStore does not support flat-map operations.
Register a table with TableRegistry.register(...) so that
ModelRepository routes all operations through the SQL path.

There is also:

Failed to find model:

and the stack trace points to:

JaloquentTransactionRepository.record
ShopTransactionPersistenceListener.onSale
ShopTransactionService.sell

So it looks like the database connection is working, but something goes wrong when EzShops tries to save the transaction.

Is this a bug in the Jaloquent transaction repository, or am I missing something in the configuration?

Also, is there a way to use a different storage backend for transaction history while keeping MariaDB/Jaloquent for player shops?

I can send the full config and stack trace if useful.

Thanks!
