Assertion error -6 (Graphviz on macOS)

I see a similar issue to issue #222 and #203 but with some differences: assertion code is ‘-6’ and I see this message terminating with uncaught exception of type NSException\n"

I did follow the steps outlined here: https://github.com/pydot/pydot/issues/203#issuecomment-533164709

I isolated the issue to the dot string: offending-dot-string.txt

with the following message: message.txt

I apologize. I am not sure how I to trouble shot the issue.

Apologies. I added the offending-dot-string.dot file to the directory and re-ran the set of commands. The output is here: output_testing-commands-with-dot-string.txt.

In the mean time, I am working to update the version of graphviz. This might take a moment (conda and the time to solve environments). But, once done, I will rerun the set of comments, investigate the issues you shared, and report back.

Thank you, Peter!

Ok, cool, that means that the upgrade really solved it and I can mention that in issue pydot/pydot#233. Thank you for taking those extra steps! And good luck with your work, let us know if you run into any problems when adding pydot to the mix!
