Multi-sheet Excel files failing to convert to HTML

Using aspose-cells in a Java environment. After upgrading from 21.8 to 21.10, multi-sheet Excel files no longer render when we try to create HTML previews of their content.
Seeing these in the logs:
“No handler found for GET /rest/…/_files_files/sheet002.htm”
“No handler found for GET /rest/…/_files_files/tabstrip.htm”

Reproduced with a very basic worksheet. Took a blank XLSX file, added a few words in a cell, and added a second sheet with a cell containing other text.

Rolling back to 21.9 works again.


Please try our latest version/fix (Aspose.Cells for Java v22.2):

If you still find the issue with latest version, kindly provide your sample (runnable) code (JAVA program) and sample files to reproduce the issue, we will check it soon.

PS. please zip Excel files or other files prior attaching here
