Description
I can create pairs plots fine on my laptop.
mcmc_pairs(mcmc_out$draws(), np = nuts_params(mcmc_out))
When I run the identical code on the Sharcnet HPC system, if I include np = nuts_params(mcmc_out), the code will fail with the error:
Error in `geom_point()`:
! Problem while computing aesthetics.
ℹ Error occurred in the 2nd layer.
Caused by error in `check_aesthetics()`:
! Aesthetics must be either length 1 or the same as the data (15000)
✖ Fix the following mappings: `colour` and `size`
Run `rlang::last_error()` to see where the error occurred.

Research direction
Start at the mcmc_pairs() entry point and the nuts_params(mcmc_out) argument using the provided reproducible snippet. Compare the R and package environments on the laptop and Sharcnet, then determine whether the same call can produce the reported geom_point() error; done means the cause is identified and the behavior is consistent or documented across environments.
