AvatarStorageProvider not found with Keycloak Docker container #2

Hi @thomasdarimont, I'm facing with a java.lang.NullPointerException thrown when AbstractAvatarResource tries to get a AvatarStorageProvider provider.

I'm using Keycloak official image (tag 7.0.1) available from here. I simply run the container mounting the ear file inside /opt/jboss/keycloak/standalone/deployments.

The deploy seems to go well, as the REST resource is effectively loaded in the system providers page and reachable through curl. The issue seems to be related only to the custom SPI. What am I missing?

Here is the complete exception log:

In the end accordingly to the module alias in jboss-deployment-structure.xml I had to add

<subsystem xmlns="urn:jboss:domain:keycloak-server:1.1">
  <providers>
    <provider>
      module:deployment.avatar-minio-extension-bundle
    </provider>
  </providers>
  <spi name="avatar-storage">
    <provider name="avatar-storage-minio" enabled="true"/>
  </spi>

to the standalone-ha.xml file.
