AppendField generates Cannot found font

[01JQTKJTFXPCJ823TVMP]

The code below (specifally the AppendField) generates a font error for some reason.
As there is no documentation on AppendField for python - I'm not sure what I am doing wrong.

Code: Select all

    bSec = doc.AddSection()

    # Insert a 3-column header in the new section
    # Column 0 -> Subject
    # Column 1 -> Security
    # Column 2 -> Version
    header = bSec.HeadersFooters.Header
    # Clear any existing paragraphs in the header:
    bSec.HeadersFooters.Header.Paragraphs.Clear()

    # Create a new table directly on the header, specifying True to enable the default borders or styles
    hfTable = bSec.HeadersFooters.Header.AddTable(True)

    # Define the table shape
    hfTable.ResetCells(1, 3)

    # Cell 0: Subject
    subjectVal = doc.BuiltinDocumentProperties.Subject or "No Subject"
    c0Para = hfTable.Rows[0].Cells[0].AddParagraph()
    c0Para.AppendText(subjectVal)

    # Cell 1: Security level
    securityVal = data.get("security", {}).get("level", "Confidential")
    c1Para = hfTable.Rows[0].Cells[1].AddParagraph()
    c1Para.AppendText(securityVal)

    # Cell 2: A doc variable field named "A1"
    c2Para = hfTable.Rows[0].Cells[2].AddParagraph()
    c2Para.AppendField("Version", FieldType.FieldDocVariable)

Code: Select all

Version is set elsewhere:

Code: Select all

    if version_in_json:
        doc.Variables.Add("Version", version_in_json)
    else:
        logging.warning("Version not found in JSON metadata.")
        doc.Variables.Add("Version", "---")


I've also tried:

Code: Select all

    # Cell 2: A doc variable field named "DocumentVersion"
    version_style = ParagraphStyle(doc)
    version_style.Name = "VersionStyle"
    version_style.CharacterFormat.FontName = "Helvetica Neue"
    doc.Styles.Add(version_style)
    c2Para: Paragraph = hfTable.Rows[0].Cells[2].AddParagraph()
    field = c2Para.AppendField("DocumentVersion", FieldType.FieldDocProperty)
    field.ApplyCharacterFormat(version_style.CharacterFormat)


which causes the same font error:

Same error.

Same error.

Hello,

Thanks for your inquiry.
Please note that when creating fields, the program loads the Times New Roman font from the system font directory. Therefore, if this font is not installed on your system, the program will return an error. Please install the Times New Roman font and retest. If you have any other questions, please feel free to write to us.

Sincerely,
William

For those ending up here using VSCode devcontainers with a Debian image.
You need to:

Code: Select all

# 1) Create a new repo config that has the main, contrib, and non-free components.
#    Adjust "bookworm" to match whatever codename you're actually on.
sudo sh -c 'echo "deb http://deb.debian.org/debian bookworm main contrib non-free" > /etc/apt/sources.list.d/bookworm.list'

# 2) Update the package lists.
sudo apt-get update

# 3) Accept the EULA for the MS fonts (so it won't prompt interactively).
echo "ttf-mscorefonts-installer msttcorefonts/accepted-mscorefonts-eula select true" | sudo debconf-set-selections

# 4) Finally, install the fonts and rebuild the cache.
sudo apt-get install -y ttf-mscorefonts-installer fontconfig
sudo fc-cache -fv
