When i trying render a docx using standard example i get this error

Traceback (most recent call last):
  File "C:\Users\megak\Desktop\study\3 курс\practic 3\giga\main.py", line 10, in <module>

                       ^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'DocumentPart' object has no attribute '_rels'. Did you mean: 'rels'?

My code:

from docxtpl import DocxTemplate

doc = DocxTemplate("t.docx")

context = {

    'text':"memememe"
}

doc.render(context)
doc.save(b"tesxt.docx")
