[NTG-context] Polar pgfplots seems to be broken

I’m drawing solar system diagrams using the pgfplots module, but the polar library seem to be broken. It looks like it is calling something with a \begin{axis}... command. Here is the error message for a short document, included below.

I’d love a fix or an idea for a work around. I’m using ConTeXt Suite (ver: 2020.12.15 10:10 MKIV  fmt: 2020.12.16), but I’ve tried it with TeX Live 2020 and the MkIV included with LMTX. Both have the same issue.


\usemodule[tikz]			% TikZ module for diagrams
\usemodule[pgfplots]		% PGFPlots module for graphs
\pgfplotsset{compat=1.17}	% Required to get new any features that could cause compatibility issues.
\usepgfplotslibrary[polar]		% ConTEXt

\startsection[title={Rectangular Plot}]
	\starttikzpicture% tikz code

\startsection[title={Polar Plot}]
	\starttikzpicture	% tikz code
