SYNTAX ERROR: No matches for: inv_gaussianvector_lpdf

My model errors with the inverse.gaussian() family - no matter which link I try (does work with the same data in lme4::lmer)…

Reprex:

library(brms)
x <- exp(rnorm(100))
d <- data.frame(x = x)

m <- brm(
  x ~ 1,
  data = d,
  family = inverse.gaussian()
)

Error:

Compiling Stan program...
