Incomprehensible error (with vapply) during compilation

[AntoineBraultChile]

Hello,
I wrote a discrete SIR model with odin. When I try to compile it, I get the followiing obscure error:

Generating model in c
Error in vapply(X, FUN, character(1), ...) : values must be length 1,
but FUN(X[[1]]) result is length 0

What is weird is that the line of the error is not indicated. (It could be related to the issue #184)
Do you have any advice to debug the code (the model is around 600 lines long)?

Thank you very much.

This is most likely an issue where there is a bug in your model but also a bug in odin trying to report this back to you. It's possible that the result of traceback() immediately after the error will be informative, but more likely that I would need your model code to reproduce
