Error when fitting. Any idea why?

[kaydadaemon]

Error in dplyr::mutate(): ℹ In argument: fit = stats::predict(curve). ℹ In group 1: Well = G7. Caused by error: ! fit must be size 373 or 1, not 2238. Run rlang::last_trace() to see where the error occurred.

Hi! Thanks for your question. Can you provide a reproducible example so that I can test it on my end?
