Tikz font in beamer export

Question

I'm exporting a presentation from an org file that includes a block of tikz code. This is my minimal working example:

#+TITLE: Beamer Question
#+AUTHOR: J. Doe
#+OPTIONS: H:2 toc:t
#+LATEX_CLASS: beamer
#+LATEX_CLASS_OPTIONS: [presentation, aspectratio=169]
#+LATEX_HEADER: \usepackage{graphicx}
#+BEAMER_THEME: Hannover
#+COLUMNS: %45ITEM %10BEAMER_ENV(Env) %10BEAMER_ACT(Act) %4BEAMER_COL(Col)

* Introduction
** Problem
*** Normal text   
:PROPERTIES:   
:BEAMER_col: 0.4   
:END:   
This is how normal text looks; with sans serif font
*** Tikz image
:PROPERTIES:
:BEAMER_col: 0.6
:END:
#+begin_src latex :file tikz.pdf :packages '(("" "tikz")) :border 1pt :results raw   % Define block styles

  \begin{tikzpicture}[    text/.style={text width=5cm, align=center}]

  \node (n) [text] at (0,0) {But if I write text in a tikz picture, it uses the default Latex font (serif)};
  \end{tikzpicture}
#+end_src

Exporting this with M-x org-beamer-export-to-pdf produces this slide:

My question is, how can I tell tikz to use the same font as the rest of the beamer presentation?

Things I've tried:

Search online. Found nothing
Export to latex file. The result is that orgmode executes the tikz code, produces a pdf (with the wrong font) and inserts the produced pdf as an image. The problem persists

EDIT: As requested, this is the latex code generated by orgmode

Can you show the resulting .tex code? Without seeing the code, this is just a guess: \tikzset{ font=\sffamily } — samcarter_is_at_topanswers.xyz
@samcarter_is_at_topanswers.xyz I edited the questions to include the latex code. As you can see, orgmode executes the code tiks code and stores the results in a pdf file, and then inserts that pdf file in the resulting presentation — juanerasmoe

The problem is that using a src block causes org to invoke LaTeX on that block and this does not inherit any settings from the document. What if you change begin_src...end_src to begin_export latex ... end_export?
