Rendering (persian, idk if it's related or not) docx template, causes this exception:

Traceback (most recent call last):
  File "/home/alireza-g14/Workspaces/Repoters-test/main.py", line 99, in <module>

Python code used:

template = DocxTemplate("template3.docx")

with open("c.json", "r") as context:
    jsonObj = json.load(context)

for id, item in enumerate(jsonObj["vulnerabilities"][0]["proof"]):
    if item.startswith("imgs"):
        width, height = scale_image(
            input_image_path=jsonObj["vulnerabilities"][0]["proof"][id]
        ) # function that gives width and height.
        jsonObj["vulnerabilities"][0]["proof"][id] = InlineImage(
            template, item, width=Mm(width), height=Mm(height)
        )

template.render(context)

template.save("output3.docx")
