docx to pdf, file link path error

[erild]

I am using the gotenberg docker to convert a docx containing relative file links into a pdf.
The link path are not kept through the convertion:
For a link file:///./annexes/dir/file.xlsx, after convertion, the link is transformed into ../../.././annexes/dir/file.xlsx instead of ./annexes/dir/file.xlsx

Expected Behavior

For a link (in the OOXML) file:///./annexes/dir/file.xlsx, after convertion, the link is should be ./annexes/dir/file.xlsx

Current Behavior

For a link file:///./annexes/dir/file.xlsx, after convertion, the link is transformed into ../../.././annexes/dir/file.xlsx instead of ./annexes/dir/file.xlsx

Possible Solution

Not really sure what the issue is, i haven't looked much into the code of the conversion yet. It may be due to the command used to launch the conversion (The link is correct when i use unoconv -f pdf testing.docx to do the conversion).
Maybe launch the command from inside the temporary directory created

Steps to Reproduce (for bugs)

testing ll.pdf
testing ll.docx

I joined a docx (and the converted pdf) where the issue is visible. To reproduce:

1. Create a docx with a link to a file or download the docx file provided
2. Launch the conversion to pdf
3. Check the link in the pdf

Logs (LOG_LEVEL="DEBUG")

Not really useful here, except for the command launch to convert

{"level":"debug","msg":"executing command: unoconv --user-profile ///tmp/45281 --port 45281 --format pdf --output /gotenberg/tmp/BNKaM8uNWfGsAzpvkbQzMDlvuDvFqvyO/0qH9WdO4R3yHZGmppRreJEGa36S8h8xe6.pdf /gotenberg/tmp/BNKaM8uNWfGsAzpvkbQzMDlvuDvFqvyO/testing.docx","op":"xexec.LogBeforeExecute","time":"2019-11-12T12:04:10Z","trace":"BNKaM8uNWfGsAzpvkbQzMDlvuDvFqvyO"}

Context

This is for delivering a archive containing the pdf and a list of assorted xls files which can be opened from the pdf (or the docx) instead of needing to browse through the folder to find the right one

Your Environment

I reproduced the issue with a simple docker run --rm -p 3000:3000 -e LOG_LEVEL="DEBUG" thecodingmachine/gotenberg:6 and a curl post request curl --request POST --url http://localhost:3000/convert/office --header 'Content-Type: multipart/form-data' --form files=@PATH_TO_FILE/testing.docx -o ./result.pdf

Hello @erild

Thank you for the well written issue!

Maybe launch the command from inside the temporary directory created

As suggested, I've tried this:

unoconv --user-profile ///tmp/40843 --port 40843 --format pdf --output 0SayLHLBOpzbIo3scrCcbN2s7QJ09GQfk.pdf testing.ll.docx

But no luck so far!

As far as I understand, unoconv resolves the / from /annexes... as the root path on the system. This is why we're getting ../../../assets because the conversion occurs in a path like /gotenberg/tmp/randomFolderName.

I've tried to update the link in the docx file with file:///./annexes/... instead of file:///annexes/... but again no luck.
