No object produced using latest CmdStanR

Just updated to latest Cmdstan and cmdstanr.

Model (including the cmdstanr example) compiles and is fitted but no object produced as per following error:

All 4 chains finished successfully.
Mean chain execution time: 34.6 seconds.
Total execution time: 45.4 seconds.

Error in !is.null(csv_contents$metadata$save_warmup) && csv_contents$metadata$save_warmup : 
  invalid 'y' type in 'x && y'

And hence not possible to access any model object.

Reinstalled cmdstanr but still same error.

Appreciate any advice to resolve this issue.

R version 4.4.1
CmdStan version: 2.35.0
(CmdStan path set to: /Users/milani/.cmdstan/cmdstan-2.35.0)
cmdstanr version: 0.7.1

macOS Sonoma 14.5 (on arch 86_64)

You need to update your version of cmdstanr, the current is 0.8.1

Yes indeed - thank you. And here I was thinking I had the latest cmdstanr!
