Error in mcv.FLORAL bind_rows()

[funnell]

Hello, I'm running FLORAL 0.3.0 like so:

> mcv_fit_0_6 <- mcv.FLORAL(
  mcv = 10, ncore = 8,
  x = as.matrix(X_0_6), y = y_0_6,
  longitudinal = TRUE,
  id = as.integer(factor(metadata_0_6$mouse_id)),
  tobs = metadata_0_6$day,
  family = "binomial", ncv = 5, progress = TRUE
)

and received this error message:

Error in `bind_rows()`:
! Argument 3 must be a data frame or a named atomic vector.
Run `rlang::last_trace()` to see where the error occurred.
