Error polygon edge not found for ggraph_signaling_path$plot

[lchan8]

Hi,

I ran into the following error when I was running the vignette: MultiNicheNet analysis: MIS-C threewise comparison - step-by-step with all details. This occurs when I am running the code to visualize the ‘prior knowledge’ ligand-receptor-to-target signaling paths. I am using multinichenetr 1.0.3.

I also got the same error when I was working my own dataset.

Hi @lchan8

Can you confirm this also happens after updating ggraph, tidygraph, and igraph to their latest versions. For me, there are no issues at all in running this code in the example vignettes, so I suspect your problem may have to do with version incongruencies.

Thank you for looking into it! My packages were all up-to-date, but I realized that when I changed font to "serif" instead of "Serif," it resolved the issue for me.
