LibreOffice 7.3 conversion tool can no longer convert .pptx to .html


I am working on a service that converts documents to pdf or html in order to display them in a browser. I am trying to update the libreoffice version from 7.2 to 7.3 and I am noticing now that it can no longer convert powerpoint documents to html.

The command I have been running is

soffice --headless --convert-to html test.pptx

I tried updating my command to specify a filter to use but that did not seem to work:

soffice --headless --convert-to html:"impress_html_Export" test.pptx

When I run the first command there is an error message saying that there is no export filter. When I run the second command I get an error that I should verify my input parameters

Does anyone know of any updates to libreoffice that would cause such an issue?

That would be a regression (and export to htm works, unlike html); please file a bug report.
