tikzCoord bug - Githubissues

When trying to create a tikz plot, I could not use tikzCoord. Here is a minimum working example to reproduce my problem:

#### Minimum working example
## Load package
library(tikzDevice)

## Tikz plot
tikz("./test.tex", width = 3, height = 3)
tikzCoord(1, 0, "a")
tikzCoord(2, 1, "b")
tikzAnnotate("\\draw (a) -- (b);")
dev.off()

There is no error in the R console, but the coordinates are all (0,0) in the tex file:

% Created by tikzDevice version 0.12.3.1 on 2020-07-04 20:13:35
% !TEX encoding = UTF-8 Unicode
\coordinate (a) at (0,0);
\coordinate (b) at (0,0);
\draw (a) -- (b);

For information, I am using vscode and my rsession is:
