Import .docx file : error 400 : Could not convert file content

[acazenave]

Bug Report

Problematic behavior
When I try the Import Docx feature, I got an error saying that the import failed.

In console I see an Error 400 :
XHR POST https://docs.numerique.gouv.fr/api/v1.0/documents/ [HTTP/1.1 400 0ms]
Response : 0 | "Could not convert file content"

I have this issue with all .docx document I tried. Even one generated by the export to docx feature from Docs.

Expected behavior/code
File should be uploaded and converted to Docs format.

Steps to Reproduce

1. Export a Docs document to docx.
2. Then got to home page and click on the import button
3. Select the local .docx file you have just download.

Environment

• Docs version: 4.8.2 (on lasuite.coop instance) don't know on dinum instance.
• Instance url:
  • https://docs.numerique.gouv.fr/
  • instance of lasuite.coop

Hi there, I am just passing by and I don't think this is bug from this solution.

From reading your stacktrace and especially ERROR DocSpec service error: url=None, it seems your settings.DOCSPEC_API_URL might not be properly initialized.

I am not familiar with this repo, so I can only recommend to read the dedicated doc page (if not already done): https://github.com/suitenumerique/docs/blob/main/docs/env.md.
