I would suggest making a branch first, then in that branch delete
poi-4.1.1.jar
poi-4.1.1.jar.Advanced_Excel.RequiredLib
poi-ooxml-4.1.1.jar
poi-ooxml-4.1.1.jar.Advanced_Excel.RequiredLib
poi-ooxml-schemas-4.1.1.jar
poi-ooxml-schemas-4.1.1.jar.Advanced_Excel.RequiredLib
Is the Advanced Excel module from the Marketplace?
The java action can’t find the required method in the poi jar file. This can happen if you have multiple versions of the poi jar file in your userlib. Duplicates may be from an older version of the module or another module that also uses poi functionality.
To fix this, I would suggest looking in your userlib folder, and removing all the poi jar files except for the one with the highest version number.
When you rebuild the project, it should hopefully work.
Good luck!
Thank you for your answer!
This is my userlib folder from what I see all the Excel Advanced related joi are all with the same version. What files should I delete?
Here it is.
