I'm trying to represent a phylogenetic tree with the following code.
ggtree(tree2, layout="circular", size=0.03)+
geom_tiplab2(aes(label=), align=T, size=0.5, hjust=0.1)
but I get the following error:
Error in `geom_segment2()`:
! Problem while converting geom to grob.
i Error occurred in the 3rd layer.
Caused by error in `check.length()`:
! 'gpar' element 'lwd' must not be length 0
Run `rlang::last_trace()` to see where the error occurred.
When I Run rlang::last_trace() I get this, which honestly I don't know what it means:
Backtrace:

I tried putting different values of linetype, linesize and lwd in geom_tiplab2 but I always get the same error. It only worked when I put linetype=NA , but then I have no lines conecting the tips of the tree to their corresponding name, and there are a lot of tips so it is quite hard to see which one is which then (having too many sequences is not the problem, I tried with a reduced tree and got the same error). Does someone know what could be the problem?
