Hi @sb2512,

Can you check if it Align POI version with your AEM SDK?

AEM Cloud SDK includes a specific version of POI. To avoid conflicts:

  • Match the version in your pom.xml to what’s bundled in the SDK.

Check which POI version AEM SDK includes (you can check this via /system/console/depfinder or webconsole) — then, in your core module:

<dependency> <groupId>org.apache.poi</groupId> <artifactId>poi-ooxml</artifactId> <version>4.1.2</version> <!-- Match this with the SDK --> <scope>provided</scope> <!-- IMPORTANT --> </dependency>

  • Use provided scope to avoid packaging it in the bundle.
