After some time, I could write a minimal example with tikz with strange error: Cannot parse this coordinate.

Can someone help me to find the bug?

I attach the file and the log.

Help very appreciate
I run

$ context --version
mtx-context     | ConTeXt Process Management 1.04
mtx-context     |
mtx-context     | main context file: /usr/share/texmf-dist/tex/context/base/mkiv/context.mkiv
