Wildfly created using Wildfly-maven-plugin raises error "Transaction is required to perform this operation"

[dafi]

I created a custom WF installation based on Wildfly-

26.1.3.Final using the maven plugin https://github.com/wildfly/wildfly-maven-plugin/

It works fine but when I try to make SQL insert from my app I obtain this error

 javax.persistence.TransactionRequiredException: WFLYJPA0060: Transaction is required to perform this operation (either use a transaction or extended persistence context)
10:47:37,259 ERROR [stderr] (default task-2)     at org.jboss.as.jpa.container.AbstractEntityManager.transactionIsRequired(AbstractEntityManager.java:880)
10:47:37,261 ERROR [stderr] (default task-2)     at org.jboss.as.jpa.container.AbstractEntityManager.persist(AbstractEntityManager.java:582)

So I downloaded a full copy of Wildfly-26.1.3.Final and the app works fine, insert, update, delete are executed correctly

My layer configuration is shown below, I know transactions is redundant...

<layers>
<layer>jaxrs-server</layer>
<layer>jpa</layer>
<layer>transactions</layer>
</layers>

What am I missing?

Env

maven 3.8.7

wildfly-maven-plugin 4.0.0.Final

JDK OpenJDK Runtime Environment Temurin-17.0.6+10 (build 17.0.6+10)

It could either be a source code bug or a config problem. Could you
please provide an example project that contains your setup and your
core part of the code which uses the transaction?

The application works fine under any Widlfly version since 18.x to 26.1.3 so the problem is releated to some missing layer, indeed I finally found the missing piece, the "ejb-lite" layer.

After adding "ejb-lite" all transactions works fine.

Thanks for your time

Okay! btw here is the document that contains the list of WildFly
Galleon Layers for reference:
