[bug] Weird failure (when hiding all connector pins)

[cmjdev]

Sorry for the lack of description. I don't know how to explain this.

The following yaml works. If I try and remove or comment out the LINK.PDM connection it fails with the following error:
graphviz.backend.execute.CalledProcessError: Command '[WindowsPath('dot'), '-Kdot', '-Tpng', '-O', 'test']' returned non-zero exit status 1. [stderr: b'Error: syntax error in line 15 \r\n... \r\n </table> ...\r\n']

The working/non-working code:

  override:
    graph:
      ranksep: '6' # Larger horizontal separation between nodes
      splines: 'true' # Or ortho?

I've looked into this a bit more.. It looks like when no pins are connected and you're using hide_disconnected_pins: true it freaks out.. Not sure if this is bug or not but I'm good now. Feel free to close this if it's as designed.
