Using the handler.js code from the readme, I get the following error in the cloudwatch logs when I run it
Error: Please verify input parameters... (SfxBaseModel::impl_store <file:///tmp/hello.pdf> failed: 0xc10(Error Area:Io Class:Write Code:16) at /home/buildslave/source/libo-core/sfx2/source/doc/sfxbasemodel.cxx:3207 at /home/buildslave/source/libo-core/sfx2/source/doc/sfxbasemodel.cxx:1783)
I have set the environment variable HOME to /tmp as advised in the readme
