LibreOffice installed, but check_libreoffice_export() reports FALSE

[njbart]

My LibreOffice installation works as expected throughout, both when using the GUI as well as in “headless” mode.

check_libreoffice_export(), however, reports FALSE, both in the R command line interface and in RStudio.

Are there any additional diagnostics available from check_libreoffice_export(), or any other suggestions what to try next?

macOS 11.6.8
LibreOffice 7.4.0.3, installed via homebrew

Weird

what does locatexec::exec_available("libreoffice") returns?

> locatexec::exec_available("libreoffice")
[1] TRUE

BTW, doconv is version 0.1.4

Same for me on Windows 11, I did not encounter the problem on MacOS.

Debugging

Settings run(echo=TRUE) in check_libreoffice_export() I get the following error:

> check_libreoffice_export()
Running "C:/Program Files/LibreOffice/program/soffice.com" --headless \
  "-env:UserInstallation=file:///C:/Users/heckm/AppData/Local/Temp/RtmpkHCdKd/lo_7180253e3216" \
  --convert-to "pdf:writer_pdf_Export" --outdir \
  "C:\Users\heckm\AppData\Local\Temp\RtmpkHCdKd\file718069c7d22"  \
  "C:\Users\heckm\AppData\Local\Temp\RtmpkHCdKd\file718069c7d22/minimal-word.docx"
Entity: line 1: parser error : Document is empty

^
[1] FALSE

Interestingly, the error also occurs when pasting the command in the Command Prompt. But then after a appr. 20 seconds (!), the process finishes and produces the file. The second time, the whole process runs much faster and correctly overwrites the file.

Quick Fix

I suspect, that this is an Libre Office issue. Not sure if this can be fixed on the R side.
A quick "solution" in R would be to increase the timeout. With run(timeout = 45, echo=TRUE) I get:

> check_libreoffice_export()
Running "C:/Program Files/LibreOffice/program/soffice.com" --headless \
  "-env:UserInstallation=file:///C:/Users/heckm/AppData/Local/Temp/RtmpkHCdKd/lo_718039b5ba1" \
  --convert-to "pdf:writer_pdf_Export" --outdir \
  "C:\Users\heckm\AppData\Local\Temp\RtmpkHCdKd\file71803e887c6" \
  "C:\Users\heckm\AppData\Local\Temp\RtmpkHCdKd\file71803e887c6/minimal-word.docx"
Entity: line 1: parser error : Document is empty

^
convert C:\Users\heckm\AppData\Local\Temp\RtmpkHCdKd\file71803e887c6\minimal-word.docx as a Writer document -> C:\Users\heckm\AppData\Local\Temp\RtmpkHCdKd\file71803e887c6\minimal-word.pdf using filter : writer_pdf_Export
